Biologically, what is the food chain? What is the relationship between the various organisms in the

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 (fragmented food chain), and parasitic 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.

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.

There are many kinds of organisms in the ecosystem, and they play different roles in the ecosystem, and according to the role they play in the movement of energy and matter, they can be classified into three categories: producers, consumers and decomposers. A food web made up of food chains.

Producers are mainly green plants, autotrophs that can make nutrients from inorganic matter, this function is photosynthesis, and also includes some chemical bacteria (such as nitrifying bacteria), they can also synthesize organic matter from inorganic matter, and the role of producers in the ecosystem is to carry out primary production or primary production, so they are primary producers or primary producers, and the biomass they produce is called primary production or primary production. The activity of the producer is to obtain carbon dioxide and water from the environment and synthesize carbohydrates (mainly glucose) under the action of sunlight or chemical energy. Therefore, only through the producer can solar radiation energy be continuously input into the ecosystem into chemical power, that is, bioenergy, which becomes the only energy source in the life activities of consumers and decomposers.

Various organisms closely connect this organism with that organism through a series of eat-and-eat relationships, and the sequence in which such organisms are linked to each other by food-nutrient relationships is called the food chain in ecology.

Tigers eat deer, deer eat grass, grass absorbs nutrients and sunlight from the soil, and dead animal carcasses decompose into the dirt.

There are many kinds of organisms in the ecosystem, and they play different roles in the ecosystem, playing the role of energy transfer and material circulation. Organisms form a food network relationship that restricts and interdepends on each other. For example, predators-herbivores and insects-birds in grassland ecology restrain each other and coexist and prosper.

The relationship between them is antithetical and harmonious. In the African savannah, carnivores represented by lions, cheetahs and hunting dogs exclusively eat herbivores, and they hunt wildebeest and even zebras, but this cruel killing is not only the need for the survival and reproduction of carnivores, but also an indispensable factor to maintain the flourishing and ecological balance of grassland plants. If there is no control of herbivores by carnivores, herbivores will develop rapidly, and when herbivores develop to a certain number, the grassland will be unbearable, the grassland will be degraded, and herbivores will lose the conditions for survival and development.

The killing of herbivores by carnivores not only controls the number of herbivore populations, but also improves the quality of herbivores in a sense.

The relationship between living things can be elaborated in several ways:

1. Mutual restraint and interdependence. Due to the food relationship, they are interdependent, and at the same time control the population population, maintain harmony and maintain balance.

2. It is conducive to co-evolution. For example, the killing of herbivores by carnivores not only controls the number of herbivore populations, but also improves the quality of herbivores in a sense. In the process of hunting, the objects of selection are often sick and weak herbivores, and for hunters, the weak hunters are also eliminated due to lack of food, which is undoubtedly conducive to the survival of the fittest, the evolution of species, and the survival of the fittest.

3. The harmonious balance of ecology is maintained between living organisms. Producers, consumers, and decomposers each play their own important role. It plays an important role in the circulation of matter and the transfer of energy.

Food websThere are often many food chains in an ecosystem, and the complex trophic relationships formed by the intertwining of these food chains are called food webs. Food webs can visually describe the trophic structure of ecosystems, which is the basis for further research on ecosystem functions.

There is an intricate universal connection between the biological components of the ecosystem through the energy transfer relationship, which is like an invisible network that includes all living things, so that they have some direct or indirect relationship with each other, which is the food web

The sequence of food chain organisms that are linked to each other by food-trophic relationships is called the food chain in ecology.

Food webs contain food chains.

The food chain belongs to the food web.

Idiom: The praying mantis catches the cicada, and the yellow finch is behind.

Big fish eat little fish. Sheep into the tiger's mouth.

Rabbit dead dog cooked. The rabbit dies and the fox is sad, and the rabbit rises and falls.

The snipe and the clam compete, and the fisherman profits.

As the saying goes: big fish eat small fish, small fish eat dried shrimp, and dried shrimp gnaw on mud.

If you want the fruit to grow well, you have to run among the bee flowers.

If you don't see a rabbit, you don't scatter an eagle.

Stealing chickens is not a recipe for rice.

There is no cat that does not eat fishy.

Afterword: The weasel greets the chickens for the New Year - not well-intentioned.

Cat Crying Mouse - Fake Compassion.

Ancient poem: Big rat big rat, no food for me.

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 (fragmented 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.

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

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 refers to:
