Biological chain: The 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 are connected to each other through a series of relationships between eating and being eaten (predation relationship), which is called the food chain in ecology. According to the relationship between organisms, the food chain can be divided into predatory food chain, carrion food chain (crushed food chain) and parasitic food chain.

Various organisms obtain the energy needed for survival, growth and reproduction in their unique ways, and the energy and substances fixed by the producer are transmitted between organisms through a series of feeding relationships, such as herbivores feeding on plants, carnivores preying on herbivores, and the chain one-way connection formed between different organisms through food is called food chain. A complete food chain is constructed by producers, consumers, and the source begins with the producer's photosynthesis locking in solar energy.

Different species of organisms form food chains due to their diets. For example, a frog eats a dragonfly, a snake eats a frog, and an eagle preys on a snake.

The food chain refers to the food network relationship formed by the mutual constraints and interdependence of organisms. They restrain each other and coexist and prosper.

It is the weak that eats the strong, and the strong feed on the weak, for example, the tiger eats the wolf, the wolf eats the sheep, and the sheep eats the grass. The chain relationship formed by these organisms.

It has been made possible to realize that if something goes wrong at any point in the food chain, disaster is imminent. When the wolves are hungry, they poach cattle and sheep, but under normal circumstances, the wolves feed on hares. From this point of view, it is the wild wolf that controls the reproduction and development of the hare, avoids the phenomenon of hare and cattle and sheep competing for food, and ensures the normal ecological environment of the grassland.

When the herdsmen realized this natural law, they became much more tolerant of wild wolves, and no longer talked about wolf color change, and beat wolves when they saw them.

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 are connected to each other through a series of relationships between eating and being eaten, which is called the food chain in ecology. For example, grass, a hare, a fox, a wolf, a river valley plant, an insect-insectivorous bird, an eagle.

The food chain is also known as the "nutrient chain". In order to maintain their own life activities, various organisms in the ecosystem must feed on other organisms.

A food chain generally consists of 3-5 links: a plant, a plant-feeding animal, and one or more carnivores. The number of organisms at different points in the food chain is relatively constant in order to maintain a natural balance.

To give you a few more formal definitions (it's normal to be different, as biologists have different understandings).

Definition 1: In the ecosystem, after a plant ingests a certain substance, it produces or itself is the nutritious food of another organism and is ingested by it, and through this series of food nutrition ties such as plants, animals, predation and food, etc., it is transferred in turn, and finally eaten by people.

Definition 2: A linear connection between various organisms in a biome due to their feeding relationship.

Definition 3: In an ecosystem, autotrophs, herbivores, carnivores and other organisms at different trophic levels, the latter in turn form a one-way chain relationship between the former for food.

Definition 4: A sequence of energy movements composed of producers and consumers at all levels, which is the embodiment of the food relationship between living organisms.

Definition 5: A chain of food relationships in a biome formed by ingestion.

Definition 6: A mode of nutrient transport in an ecosystem in which organisms in turn feed on other organisms.

Definition 7: The primary energy produced by plants in an ecosystem is a kind of food nutrition chain between eating and being eaten through a series of transformations by organisms.

Organisms prey on other organisms in order to obtain energy, forming food links that are linked to the food chain.

In the ecosystem, there is a relationship between consumers and producers who eat and be eaten, forming a food chain.

In the ecosystem, after a plant ingests a certain substance, it produces or itself is another organism's nutritious food and is ingested by it, and through this series of food nutrition ties such as plants, animals, predation and food, etc., it is transferred in turn, and finally eaten by humans.

In a biome, various organisms form a linear connection with each other due to their feeding relationship.

The sequence of energy movements, composed of producers and consumers at all levels, is the embodiment of the food relationship between living things.

Chain-like food relationships formed by feeding in biomes.

The nutrient structure of an ecosystem is a mode of nutrient transport composed of organisms that feed on other organisms in turn.

The primary energy produced by plants in the ecosystem undergoes a series of transformations through organisms, forming a nutrient chain relationship between the food that is eaten and eaten.

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 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, which is called the food chain in ecology. According to the relationship between organisms, the food chain can be divided into predatory food chain, carrion food chain (crushed food chain) and parasitic food chain.

Literally, one creature eats another, for example, a cat eats a fish, it can be expressed as a fish cat, and of course a creature can take many creatures as food, which becomes a food web ......

As the saying goes: big fish eat small fish, small fish eat dried shrimp, and the mantis is not miserable, and the yellow finch is behind.

Every animal, both a foodie and a eaten, forms a chain called a food chain, and the food chain is open.

At the bottom of the food chain are the animals that feed on plants, and they only have a portion to be eaten.

At the top of the food chain are the most ferocious carnivores. They cannot be eaten.

It refers to the chain relationship in which various organisms in the ecosystem are connected by food.

Sometimes I'm really not.

Sometimes I feel like I'm not worth it.

We should have to go home when we have time, right?

The food chain is a food-bound relationship in which various organisms in the ecosystem must feed on other organisms in order to maintain their own life activities.

The food chain is actually the relationship between solar energy from one living thing to another, that is, the flow and conversion of material energy through the food chain.

The term food chain was first coined by the British animal ecologist Elton (in 1927. The chemical energy stored in the organic matter in the ecosystem is transmitted layer by layer in the ecosystem, and in layman's terms, it is a series of organisms that closely link this organism with that organism through a series of eating and being eaten, and the sequence in which this organism is linked to each other by the relationship between food and nutrition, just like a chain, one link after another, which is called the food chain in ecology. In short, in an ecosystem, a connection between various organisms due to food is called a food chain.

The food chain is also known as the "nutrient chain". It refers to the chain relationship in which various organisms in the ecosystem are connected by food.

This feeding relationship is actually the relationship between solar energy from one organism to another, that is, the flow and conversion of material energy through the food chain.
