Today I watched the third episode "Tropical Rainforest" of the documentary "Our Planet" with my daughter. The tropical rainforest I imagined looks like: the first is very hot, the second is rainy, and the third is many and unique animals and plants. This episode mainly revolves around the clue of geographic location to describe the living conditions of animals and plants in the tropical rainforest. The first is Congo, where we mainly talk about two animals, gorillas and elephants. Gorillas, the gorillas here are called silverback gorillas, they get salt by eating salt-rich aquatic plants. Elephants consume salt in two ways. One is to use elephant trunks to absorb salt from the soil; the other is to drink directly from mineral-rich water sources to absorb salt. Next is New Guinea, the youngest tropical rainforest at just 18,000 years old. Describe how several species of birds mate. Twelve cyclone birds, with special decorations on their tails, courtship by tickling their mates' faces with their tails; black sickle-billed bird of paradise, which changes into a less bird-like shape and attracts mates through unique demonstration skills; west six-line paradise Birds, courtship by cleaning territories and performing shows. Then comes Borneo in Southeast Asia, where there are already 1. 300 million years. It mainly talks about a velvet bug that existed in the age of dinosaurs, which uses a "glue gun" to catch insects. It also talks about a plant, pitcher plant, that obtains nutrients through the excrement of mountain shrew, ant carcasses and sediments of colored bats. Then we will go to the Philippine Islands, where we mainly talk about how the ape-eating eagle overcomes fear and learns to fly. It is tempered by wind and rain in the natural environment, slowly exercise self-confidence, plus learn some skills, when self-confidence and skills match, it learns to fly. Then I talked about the largest rainforest, the Amazon Basin, which accounts for half of the rainforest on the earth. It is rich in species. There are more than 1,000 species of frogs and more than 2 million species of insects. The jaguar is the number one predator here. Here is mainly the black spider monkey as the protagonist, and it is told that it obtains salt in the salted land. Then there are leafcutter ants, superorganisms with a collective function in a colony of millions. It uses the upper jaw to cut open the leaves, which hardens the leaves by creating high-frequency vibrations, making them easier to cut. Its lair, up to 8 meters deep, has thousands of interconnected rooms. Ants and bacteria work together to control pathogens and avoid destroying fungi that grow using harvested leaves. Finally, I came to the swamp forest in northern Sumatra, Indonesia, and told how the orangutan learned a lot of skills from its mother. First, how to build bridges between trees; second, learn what to eat and how to eat; third, learn to catch ants; fourth, learn to conquer treetops; fifth, learn how to find ants; sixth, learn how to Eat wasps; Seventh, learn to use sticks to make tools, and then pick out insects. There is also a plant, oil palm. We humans have kept a lot of this single species, taking over the territory of other species. Slowly, I saw that the area of the rainforest is getting smaller and smaller. This is what impressed me the most when I watched this documentary. It is everyone's responsibility to protect the environment, and it is urgent.
