The cold wind between the Earth Pulse 1 and the two levels struck, and the penguins pondered. The polar bear had not eaten for five months, lost half of its body weight, and continued to feed the cubs. The mother polar bear took the cubs to hunt seals, and half of the cubs fell into the ice water and died. Reindeer travel 3,000 kilometers of tundra in search of food. The taiga in the Arctic has one-third of the world's trees, and the conifer leaves cannot be eaten, so no animals can survive here. The Russian Far Eastern leopard is endangered. 300,000 Russian duck-faced ducks migrate to South Korea in winter. The bird of paradise that dances ballet and cleans the stage is fun. Deserts cover one-third of the world's surface and are increasing in size every year. Elephants, buffaloes and horses in South Africa travel thousands of miles in search of water for the Okavango. African wild dogs are very large, and they hunt one at a time, and they work as a team to hunt impalas. Male penguins are good dads.
2 The lion-tailed baboons in the majestic high mountains of Ethiopian plateau live on the cliffs, and they chat and exchange feelings while combing each other's hair in the morning. They eat grass for a living. They get along well with sheep. The wolves are out at night. Avalanches can reach speeds of up to 400 kilometers per hour. In the Rocky Mountains, male bears eat cubs and female bears protect cubs. It is not easy for snow leopards to drag their prey back to their dens. Other bears hibernate in winter, but giant pandas have to forage in winter because they cannot store fat from bamboo. In summer, pandas hide in caves and take care of their cubs for a month. Because of the lack of milk, the red pandas grow very slowly. Panda cubs can only open their eyes three months after birth, but very few survive to adulthood. One in ten people who climb Mount Everest die on the way. In order to reach India, the Leopard Crane must fly over the Mount Everest mountain range, and will be eaten by golden eagles on the way. Tropical rainforests cover 3% of the earth's surface, and animals and plants account for 50% of the world.
3 Freshwater resources Angel Falls has a drop of nearly 1,000 meters. Spoonfinger prawns in rapids are fun. The largest amphibian in the world is the giant salamander, which is two meters long. They have a slow metabolism and can live for more than 80 years. Salmon traverse the northern hemisphere, migrating hundreds of kilometers to spawning grounds, as there are few predators upstream for eggs and fry. Grizzlies can fish. Intermountain jet streams are the largest erosive forces on Earth. For example, the Grand Canyon in the United States is 800 meters deep and 1,600 kilometers long, which is clearly visible in space. Ganges of otters in India's Ganges massage each other, cooperate in fishing, and jointly chase away crocodiles. The five-meter Nile crocodile attacked the drinking wildebeest that looked like a buffalo, taking more than an hour to drown the wildebeest after biting it. The Great Rift Valley contains three of the largest freshwater lakes in the world. The fish in the lake build mounds on the bottom of the water, which are courtship sites. Adult cichlids hold small fish in their mouths to prevent predation. The nocturnal longjaw fish uses electromagnetic induction to catch sleeping cichlids. The mosquito larvae under Lake Malawi are very cute, like rag dolls. The mosquito swarms on the lake are mating, and it looks like a smoke column, as if the lake is on fire. Lake Baikal in East Siberia is 600 kilometers long and 1,500 meters deep. Its freshwater reserves account for one-fifth of the total freshwater of the world's rivers and lakes. The lake is covered by a one-meter-thick ice layer for five months every year. There are freshwater seals here. The Amazon River Basin covers one third of South America. Freshwater dolphins with rat-like calls cooperate to drive schools of fish into freshwater areas, where they hunt. On the surface, it seems that the fish jumping out of the sea seems to be happy, but in fact they are escaping and killing. The male puffer fish holds a stone in the water, indicating that he has strong ability and woos the female. Iguazu Falls is 2400 meters wide. Spectacled caiman looks so terrifying, eating a pink spoonbill that accidentally fell from a tree. Schools of fish eat fig fruit that has been dropped into the water. There are cynomolgus monkeys living in the mangroves. They pick up fruit from trees that have fallen into the water and can snorkel in the water for 30 seconds. Snow geese flying in flocks are like flakes of snow.
4 Cave Labyrinth The Mexican Swallow Cave is up to 400 meters deep and has a lot of skydivers. The fireflies in the deep caves spit out fluorescent beads, which look like stars, stick to the curious light insects, and then digest them. The limestone that covers 10 percent of the earth's surface is formed by the deposition of minerals from conch and coral. Borneo Deer Cave is the largest underground river cave in the world (washed out by carbonic acid in rainwater containing carbon dioxide). The feces provided by bats are the source of the food chain for other creatures in the cave. Cockroaches eat feces and bats that fall down. Crabs also eat feces. Cockroaches eat cockroaches. When the bats go out to eat insects in the evening, the peregrine falcons go to catch the bats to eat. Swiftlets echo-locate their nests in the dark. Bird's nest is built entirely on saliva in thirty days. The calcite particles in the water droplets in the cave eventually form hanging stalactites, which can form on the ground if the droplets fall too fast. The Mayan culture 500 years ago relied entirely on water from 560 kilometers of underground caves. There are not many rivers in the Yucatan peninsula, and the roots of the forests penetrate deep into the water in the underground caves for moisture. Unlike fresh water, which does not corrode limestone, sea caves are formed by the impact of waves. Cave angelfish live in waterfalls and feed on bacteria in rapids. Wild Texas salamanders resemble lean albino pigs. Snots are actually bacterial colonies that live on hydrogen sulfide gas and drip sulfuric acid out. They feed mosquito larvae. Hydrogen sulfide gas in underground oil reservoirs is oxidized to sulfuric acid in water, but fish survive in water. The American Agave Cave has a 200-kilometer-long tunnel formed by sulfuric acid erosion. The underground cave has calcium sulfate crystals, which is very beautiful. Crystal Lamp Hall.
5 Fantasy Desert
One-third of the land on Earth is desert. Wild Bactrian camels eat snow up to ten liters a day, and males use their tails to tap their buttocks to attract mates. The Mongolian Gobi lacks water because the Himalayas block water vapor. The Sahara Desert, the size of the United States, is the largest source of dust in the world. The sand dunes in Namibia are more than 300 meters high. The stones in the desert will eventually be broken into grains of sand by the wind and disappear. The driest continent in the world is Australia. The surface temperature can reach seventy degrees, and kangaroos hide in the shade, rubbing saliva on their forearms and evaporating to cool down. The top layer of soil has to be scraped off, the soil below is relatively less hot. Sand foxes have large ears and can dissipate heat. At night, the temperature of the desert dropped by thirty degrees, and at this time the toads in the ground appeared. Chile's Atacama Desert can go without rain for 50 years, and alpacas can store water the most. To survive here, they eat cactus flowers to replenish water. Because of the ocean current mist, the cactus can survive. Utah desert. Namibian elephants are the hardest animals in the desert, walking 80 kilometers every day in search of food. Lions don't climb over sand dunes, so the antelope over the dunes escapes the lion's pursuit. Death Valley desert is the hottest place on earth, but a heavy rain can make the seeds that have been sleeping in the ground for 30 years sprout and grow grass, and then the eggs of locusts for 20 years start to hatch and eat grass, multiply, and form clouds by thousands, Eat almost all the plants that pass by.
6 The frozen world Antarctica is the size of the United States. Male penguins use their stomachs to glide across the snow to avoid strenuous walking. Penguins nest and breed on bare rock, and the piled-up feces are a patch of pink. Below 1,500 meters of ice in Antarctica are mountains. Antarctic snow petrels fly 430 kilometers to Antarctica to breed, and skua will eat them. In summer, humpback whales travel 8,000 kilometers to the Antarctic Peninsula to feed on krill, and many cooperate in a circle. Winter freezes and Antarctica doubles in size. At this time, life fled Antarctica, but emperor penguins went to Antarctica to breed inland. Male penguins sing love songs to attract the opposite sex, monogamous. The female penguin takes a lot of effort to lay eggs, and she has no energy to incubate the eggs, so they are handed over to the male penguins. At this time of minus twenty degrees, the handover of eggs must be very fast. Female penguins go back to the beach to forage, male penguins gather in groups to keep each other warm, and eggs are kept under their respective feet. The male penguin keeps changing positions, you are in the middle for a while, and he is in the middle for a while. They are silent, as if meditating or praying. The temperature was minus sixty at this time. There is no sunlight at the extreme night, and the wind is raging. In the middle of the North Pole is the ocean, surrounded by land. When eiders fly over the North Pole, they rest in ice caves (unfrozen seas) at night, and they can dip into the water to eat mussels during the day. Musk oxen eat plants under the ice in the Arctic, and ptarmigan and rabbits use musk ox to break the ice to eat grass, attracting the attention of arctic foxes. Arctic foxes and wolves eat young musk oxen. Polar bears eat seals. Polar bear cubs often have one that does not survive the first year. When the ice thaws, it can't support the polar bear's weight, and it can't catch seals. The ice melted and the seabirds flew. Puffins are a bit like penguins. Arctic Skuas nest and lay eggs and will attack any intruder, including cows, elk, and foxes. When the ice surface melts, the female polar bear returns to the shore to take care of the cubs, while the male polar bear swims in the sea, waiting for an opportunity to catch seals resting on the ice. It swam for several days and finally reached land. But walruses on land weigh up to a ton, have a meter-long tusk, and have too thick fur, and they form a circle to protect baby walruses. Walruses are mild-mannered and will not aggressively attack polar bears. The polar bear was unsuccessfully caught and fractured. Global warming, the melting of the Arctic ice in advance, is the fate of polar bears, they will starve to death. The male penguin has not eaten for four months, and he has a bite of food in his mouth for the hatchling penguin to eat. The polar night has passed for a month. The female penguin came back with a belly of food, and the male penguin handed the little penguin to the female penguin (they remember each pair very clearly and can't get it wrong) to feed. When the little penguin grows up, if it gets lost, either no one wants it, or the female penguin whose child died will rush to get it. The scramble often ends with small businesses Goose was crushed to death. The lost little penguin (Lu Chi) will soon freeze to death. Polar bears are mostly solitary.
7 Great Prairie
The Mongolian gazelle is on a great migration. There are no trees on the grassland, and eagles can only nest on the ground. Lightning caused wildfires in the grasslands, gazelles had to run away, and the old, the weak, the sick and the sick were burned to death. After the grassland is burned, the grass roots regenerate and have a strong ability to repair. The savannah of East Africa can support 2 million wildebeests. The wildebeests devour the grass roots, but the grass grows quickly. The tundra in the Arctic Circle is about the size of Australia. In winter, five million snow geese migrate from the Gulf of Mexico to the tundra to breed, traveling 5,000 kilometers for three months. Snow geese have only one partner in their life. They eat grass for a living. The fox mother must catch the little snow geese for the little fox to eat. The little fox's food intake increases, so it may not be able to feed. There used to be 60 million bison in the prairie of North America. Because of human hunting, the number was reduced to more than 1,000 100 years ago. After that, it was strictly protected and increased again. Only a few bulls have the right to mate, and they fight for it. The Qinghai-Tibet Plateau, the highest grassland in the world, still has snow in summer, but still has the need for plants to support animals. The Himalama Mountains blocked the clouds, causing the Qinghai-Tibet Plateau to be unusually dry. Two male and Tibetan wild donkeys are running, seemingly playful, but in fact they are fighting for territory. The female wild donkey came and went freely, and its whereabouts were strange. The Tibetan wild asses have their footprints all over the plateau. They find an oasis, enjoy themselves for a few hours, and then leave resolutely. The grazing plateau pika's nests are sometimes occupied by birds such as ground woodpeckers, but birds can provide them with early warning of danger. The pika-eating Tibetan fox has a square face and looks weird. The southern foothills of the Himalayas receive abundant rainfall. Elephant grass is the tallest grass in the world and grows taller than an elephant. The male Bengal bustard in the grass has to jump up and down in order to court a mate. Rhinos are like ancient primitive beasts. Ji pig is the smallest and most precious wild boar, about the size of a hare. Most savannahs are followed by a dry season. The mother elephant king led the elephant herd to find the pond that rescued them a few years ago. They compete with the lion for water and drive the lion away. At night, thirty lions with better eyesight besieged a lone elephant, climbed on the elephant's back and bit the elephant's neck. When the rainy season comes, the baboons walk in the water, eat grass stems, snails, it is very interesting.
8 The plumage of a certain bird of paradise in the rainforest opens like bright blue eyes. The fig tree fruit is attached to the branches and bears fruit throughout the year, which many animals love to eat. Elephants eat dirt in water for minerals.
9 Diverse shallow seas Shallow seas refer to the water depths of more than 200 meters by the sea. Shallow seas only account for 8% of the ocean's area. Humpback whales sing to attract companions. The female humpback spends five months in the equatorial waters where there is no food for her, so she starves, breastfeeds her calf and lifts her to the surface to breathe, because she is still relatively fragile. The female humpback whale has been living on the fat in her body, on the verge of death, when the calf grows up, she will leave it to the temperate waters. Corals live in symbiosis with algae. The pygmy seahorse is less than two centimeters long, disguised as coral. They collide for territory. Sea snakes lay their eggs on land but hunt in the sea. They are slow in the water, so they have to go to coral reefs to find prey. In coral reefs in Indonesia, they cooperate with toucans to hunt together, inside and outside. Seagrass on the shallow seabed in Australia has transformed the seabed into a savannah, supporting herbivorous dugongs (mermaids). Dugongs eat only seagrass, and they can grow up to three meters in length and weigh half a ton. The snout dolphins are fishing on the waves, which is much easier. The cormorants on the Persian Gulf are hot in the desert, gasping for breath, but there are no natural predators on land, so they are stuffy here. The distance between their nests is such that they cannot peck each other. Three-quarters of the oxygen in the atmosphere is produced by marine algae. The salps eat seaweed, and they form chains that can be as long as fifteen meters. They are like small cups, filtering algae. Krill are the most abundant animals in the world, and they provide food for fish. Temperate shallow seas are the most densely populated. At the summer solstice, nutrients run out, algae die, and biological chains collapse. The fluffy ball-like sea urchins eat the roots of giant algae, and their teeth are razor-sharp. The sunflower starfish is one meter long and is a large predator that eats snaketail starfish. It can also squeeze out its stomach to eat sand dollar sea urchins. Great white sharks prey on fur seals only in cold waters. The lower the water temperature, the stronger the wind and waves, and the richer the nutrients. Fur seals usually eat krill, but sometimes penguins.
The 10-season forest Taiga taiga is the size of the tropical rainforest combined and accounts for one-third of the global forest area. They only have one month of growth a year. Lynxes are like big cats and don't show up in the same place twice. Wolverines live in icy areas all year round and can prey on elk larger than it, and are gluttonous animals. Needles are difficult to feed, so animals are scarce. Pine marten like to catch squirrels in mating because they let their guard down. Birds learn to fly, they have to try again and again. The bristlecone pine has the longest lifespan at 5,000 years, sprouting before the birth of the pyramids, and lived three thousand years before the birth of Jesus. The mandarin ducks born twenty-four hours in the forest have to learn to fly down from tall trees, and their wings are still very small at this time. There are fallen leaves underneath. The larvae of Bruder's cicada can lie dormant in the ground for 17 years, and then come out on a summer night, hundreds of millions of them will be dispatched, and they will emerge overnight. After being fed by squirrels, toads, birds, foxes, etc. during the day, the remaining cicadas mate and lay eggs. Die, and then it will be 17 years before they can be heard. Their carcasses provide a lot of nutrients to the trees. Affectionate-eyed Far Eastern leopards eat carrion abandoned by vultures. The female leopard has to raise the cubs for a year or two, which is a bit heavy. The Indian teak forest lacks water in summer, and the trees lose their leaves. The sika deer followed the monkeys to eat the flowers of saffron to replenish water. Madagascar baobab trees bloom at night, with buds like bananas. After flowering, the little-billed lemurs come to eat the nectar, and the hawkmoths also eat them to help pollinate, and then the little-billed lemurs eat the hawkmoths.
11 The largest fish in the infinite depths is the whale shark, which weighs 30 tons and is 12 meters long. It feeds on plankton, but also eats bait fish along with tuna. Usually sharks have a good sense of smell, and whitetip sharks can stalk their prey, with drinking fish following it and eating food scraps. The dolphins, which are good at using sonar positioning, besiege the horse mackerel, and the seabirds go into the water to attack the fish, which seems to be cooperation. At night, underwater plankton swim to the surface. Manta rays are large and eat plankton. Sea snow refers to small organic debris that falls from the surface of the sea into the sea. Sea spiders are close relatives of shrimp and crabs. In the deep sea there are Dumbo octopus and vampire squid. The bottom of the Atlantic Ocean is divided in half by mountains, and the thick sulfide smoke spewing from the center of the earth feeds the bacteria, and the shrimp eat the bacteria. Without sunlight, it survives on the energy of the earth's core. The sea whip is beautiful and spiral. Swimming consumes very little energy. The nautilus eats only one meal a month, and it swims backwards, making it difficult to see where it is swimming. Its sensitive tentacles can sense traces and detect the traces of natural enemy octopus. It will go back to the deep sea to hide before dawn. Dolphins use sonar to locate and hunt in teams. The ocean wanderer, the sunfish, eats deep jellyfish below 1,000 meters, and sometimes swims to shallow waters to let the reef fish clean it up. Butterflyfish were also fed the thread parasites on it. Frigatebirds can fly for months on end. Baby turtles hatch on land and are likely to be drowned by huge waves on the way back to the sea. The turtles that survive 20 years later undertake the task of inheriting the family. Their feeding grounds are thousands of miles away. Female sea turtles travel thousands of miles without food for two months, returning to isolated islands and land to lay eggs. Sailfish constantly change colors to warn their companions, otherwise they may stab each other. Blue whales can reach 200 tons, twice the size of the largest dinosaurs. They feed on krill. Now that the environment has changed, plankton has decreased, and the number of blue whales has decreased from 300,000 to less than 9,000. Humanity controls the survival of the rest of life on Earth.
