Food chain analysis of organisms, the difference between biological chains and food chains

Belch. Nothing good or bad. At the high end are basically mammals, with emotions and IQs; At the low end, like aquatic plants and so on, they don't have the ability to feel, and they don't feel pain when they are bitten. The worst thing is that there is a brain in the middle and is bitten, like a deer or something, very miserable.

Biological chains are all circular. Like the game, one dies and the other fills in. Every living thing is part of the biological chain and is at its mercy.

There is nothing good or bad about biological chains! Each other is interdependent, and no one can do without it! If one of these links is missing, it will bring disaster or even destruction to this food chain population! So there is no such thing as the best location you say!

The relationship between the various organisms in the food chain and the food web is one of interconnectedness and interdependence.

The food chain and food web are the trophic structure of the ecosystem, and the organisms in the food chain and the food web are interrelated due to the food relationship, and they are interdependent and mutually restrictive, such as the change in the number of any kind of organism in the food chain or food web, which will affect the survival of other organisms, because the change of one of the components often causes corresponding changes in other components, and even causes changes in the entire ecosystem.

The organisms in the food chain and the food web form a chain due to predation, and if one component of the chain changes, it often causes corresponding changes in other components, and even causes changes in the entire ecosystem.

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.

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.

The food chain is the transmission of energy fixed by plants in the ecosystem through a series of feeding and feeding relationships, and we call the one-way nutrient and energy transfer relationship between organisms called the food chain. The food chain is one of the specific manifestations of the trophic structure of the ecosystem. It is divided into pastoral-food food chain and carrion-food food chain.

The latter is when animals and plants are broken down by bacteria and fungi after death, and energy flows directly from the producer or the dead animal residue to the decomposer. In tropical rainforests and shallow water ecosystems, this type of food chain occupies an important place. In the pastoral-food chain, there are various consumer animals, which are established by living organisms in the relationship of predation and food, and energy flows along the path from producers to consumers at all levels.

Generally speaking, the energy in an ecosystem is about 90 percent lost as it travels from one link to another along the pasture food chain.

The biological chain refers to the interdependent chain relationship formed by animals, plants and microorganisms providing food to each other, and the biological chain can also be understood as the food chain in nature. Whereas, the food chain refers to the relationship between consumers and producers who eat and are eaten.

The biological chain maintains the natural quantitative balance between species, and this relationship is easily seen 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.

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. 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.

Its number is relatively constant to maintain a natural balance.

There are at least 2 organisms in the food chain. As long as there is a predatory relationship, the food chain can be formed, so there must be at least two organisms, but within a certain range, the food chain must be from the producer to the highest consumer, to be a complete food chain, and the arrow must be directed from the lower consumer to the higher consumer.

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.

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.
