The subsection is as follows: Web of Life.

Dense forests, vast grasslands, are inhabited by a variety of animals, the plant species are rich and colorful, and the animals are infested in groups.

All animals feed directly or indirectly on plants, and the relationship between plants and animals is very close. Plants also provide a place for animals to rest, a place to shelter; Animals also help plants spread seeds and peck pests

Biologist Charles Darwin once observed such an interesting fact in the English countryside: wherever there are many cats, the clover grows particularly luxuriantly, and cats and clover can be said to be incompatible. What is the truth behind this?

Darwin, who studied carefully, finally discovered the secret. It turns out that clover relies exclusively on soil bees for pollination; The honey brewed by the earth bee is often eaten by voles, and the voles also destroy the hive. In this way, there are more voles, fewer earth bees, and fewer opportunities for clover to pollinate.

The natural predator of rats is cats, and when there are more cats and fewer rats, there are more earth bees, and there are more clover pollinators, so they will naturally grow luxuriantly.

Cats and clovers seem to have nothing to do with each other, but with the addition of the wesp and vole, they form an interconnected chain - the food chain.

There are countless food chains in nature, and each link is criss-crossed, complex and diverse. The grass is eaten by the sheep, and the sheep are swallowed by the tiger; Rats eat grain, owls catch rats ......A plant is often eaten by a variety of animals: sheep graze, cows and horses also graze; An animal tends to eat several foods:

The sparrows eat the grain and the worms; One animal is often eaten by a variety of animals: wolves and leopards, like tigers, eat cows and sheep

As the saying goes, "Big fish eat small fish, small fish eat dried shrimp, and dried shrimp eat algae." "These are even more common things in rivers, lakes and seas.

In nature, various organisms form a "food chain" in this way, and this interdependent and mutually restrictive relationship between animals and plants forms an intricate web - the web of life

Part 1 to 2, meaning: The relationship between plants and animals is very close, part 3, part 4 to 5.
