What is the food chain? Write your homework, solve!

The biological chain refers to the interdependent chain relationship formed by animals, plants and microorganisms providing food to each other. .

This relationship is easy to see in nature. For example, where there are trees, there are often birds, and where there are flowers, there are often insects.

Plants, insects, birds, and other organisms are bound together by a chain of organisms, dependent on each other to live and die. .Examples of biological chains are often all around us, and they benefit humanity immensely.

For example, the leaves and fruits grown by plants provide food for insects, insects become a food source for birds, and with birds, there will be eagles and snakes, and with eagles and snakes, rodents will not become plagued ....... When animal droppings and carcasses are returned to the soil, microorganisms in the soil break them down into simple compounds that provide nutrients to the plant and cause it to grow new leaves and fruits.

In this way, the biological chain establishes a healthy cycle of substances in nature. .The biological chain can also be understood as the food chain in nature, which forms in nature"One thing descends one thing"maintains the natural quantitative balance between species.

Humans and nature are also connected through the food chain. Human food is mainly derived from plants and animals. Plants and animals are nourished from the natural environment before they grow.

If these animals and plants contain ingredients from environmental pollution, it is dangerous for people to eat them. Take the aquatic products.

The chemical energy stored in organic matter in the ecosystem is transmitted layer by layer in the ecosystem, and in layman's terms, it is a sequence in which various organisms closely link this organism with that organism through a series of eating and being eaten, and the organisms are linked to each other by food and nutrition relationships, just like a chain.

Submarine food chain.

The sub, linked by the other, is ecologically known as the food chain. According to the relationship between organisms, the food chain can be divided into predatory food chain, carrion food chain (fragmented food chain), and parasitic food chain. In an ecosystem, a connection between various organisms due to food is called a food chain

The food chain The chemical energy stored in organic matter in an ecosystem is closely linked to organisms through a series of eat-and-eat relationships, and the sequence in which organisms are linked to each other by food-nutrient relationships is called the food chain. According to the relationship between organisms, the food chain can be divided into predatory food chain, fragmented food chain, parasitic food chain and saprophytic food chain.

In an ecosystem, the chain structure formed between different organisms due to the relationship between eating and being eaten is called the food chain.

I eat you, you eat him, he eats her, she eats it.

Just as a tiger eats a sheep, and a sheep eats grass.

The chemical energy stored in organic matter in the ecosystem closely links organisms with each other through a series of eat-and-eat relationships, and the sequence in which organisms are linked to each other by food-nutrient relationships is called the food chain. According to the relationship between organisms, the food chain can be divided into predatory food chain, fragmented food chain, parasitic food chain and saprophytic food chain.

In the ecosystem, the chain structure formed between different organisms due to the relationship between eating and being eaten is called the food chain (e.g., rabbits eat grass, foxes eat rabbits: grass rabbits fox).

What is the food chain? For example, big fish eat small fish, small fish eat dried shrimp, dried shrimp eat aquatic plants, and so on cycle is a kind of food chain, and the one that eats the bad is the food chain.

The food chain is like a chain, which binds producers and consumers together and forms a network.

It's the food web.

The winter vacation is coming to an end, in this very happy holiday, I feel extremely happy, on the New Year's Day, our whole family went to the grandparents' house, the door of the grandparents' house was pasted with the red Spring Festival couplets, in the hometown, I spent a happy New Year, when we were leaving, my grandma stood up, grandma said to me with a kind smile: "Child, you have grown a year taller, well, this is grandma to give you the New Year's money, but also grandma's little heart, accept it."

I accepted the New Year's money my grandmother gave me and hugged my grandmother tightly. During this winter vacation, I not only felt extremely happy, but also got kindness.

The first is that everyone wants to sleep, do you want to read? What time is it in the evening? If it's too late, it's your fault to affect the rest of others, if it's very early, all of them have to sleep, you can go to the library to read and study, be optimistic and cheerful in the face of life, and don't worry about some problems that could have been solved perfectly.

I still have to review whether I have done something unconventional.

For example: big fish eat small fish, small fish eat dried shrimp, and dried shrimp eat mud balls.
