    The substances in the food chain are cyclic and the substances are passed along the food chain.

    Introduction: 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 eating and being eaten relationships (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.

    Features:1Bioenrichment.

    If a food web composed of a food chain of toxic substances is absorbed by the lower parts of the food chain, such as by grass, although the concentration is very low, does not affect the growth of grass, but the rabbit eats grass after the toxic substances are difficult to excrete, when it often eats grass, toxic substances will gradually accumulate in its body, eagles eat a large number of rabbits, it is not easy to decompose and difficult to discharge toxic substances will further accumulate in the eagle's body. Therefore, the food chain has a cumulative and amplified effect, which is called bioaccumulation.

    2.Energy flows in one direction, decreasing step by step. A food chain is a food path that connects different species in a community in terms of populations of organisms.

    The energy and nutrients in the food chain are transmitted between different organisms, and the transmission of energy in the food chain is characterized by one-way conduction and gradual decrease. A food chain generally consists of 3 to 5 links. (Since the food chain transmission efficiency is 10% 20%, it cannot be extended indefinitely, there is a limit).

    The food chain rarely includes more than six species, because the energy transferred decreases a little bit with each stage or feeding level, so-called"One mountain can't accommodate two tigers"That's it.

    3.The predatory food chain starts with the producer and ends with the animal that is not eaten by other animals, i.e. the highest trophic level, with no interruptions in between, no non-living matter and energy and decomposers, i.e. only producers and consumers.

    Summary. There is no decomposer in the food chain because food describes the food relationships between various organisms in an ecosystem. The food chain does not involve the process of decomposition of matter, so there are no decomposers in the food chain.

    However, the role of decomposers in the material cycle is very important because they help convert organic matter into inorganic matter so that these substances can be absorbed and used by other organisms. Therefore, in ecosystems, decomposers also play an important role in the food web.

    The transmission path of the material rot cycle is carried out in the food web or food chain, and there are decomposers in the material disturbance cycle, but there are no decomposers in the food chain.

    There are no decomposers in the food chain, and this is because food describes the food relationships between various organisms in an ecosystem. The food chain does not involve the decomposition of matter, so there is no decomposer in the food chain. However, the role of decomposers in the material cycle is very important because they help convert organic matter into inorganic matter so that these substances can be absorbed and used by other organisms.

    Because of this in the case of cracked rocks, decomposers also play an important role in the food web in ecosystems.

    But the way of the material cycle is carried out in the food chain or food web, doesn't it mean that there are no decomposers in the food chain, so how can it be carried out?

    That's what I'm asking.

    Next time I won't take the order, it's really a waste of time waiting here, alas, thank you.

    The main thing is that the concept is wrong, there are no decomposers in the food chain, there are decomposers in the food web.

    So you're talking about being in the food chain, and that's no.

    You need to distinguish between the food chain and the food web.

    A food web is a complex nutrient structure formed by many food chains that are intertwined with each other, and there can be no decomposers.

    In the food web, decomposers are responsible for breaking down organic matter in the food chain into inorganic matter, allowing these inorganic matter to flow through the ecosystem.

    The food chain simply describes which organisms eat which organisms.

    What I want to ask is that the way of the material cycle is carried out in the food chain or the food web, doesn't it say that there are no decomposers in the food chain, so how does it work?

    The decomposer is not a matter of who eats whom, so he does not belong to the food chain, the food chain is simply who eats and who cultivates the first brother. But he has a job in the food web, and he has to break down the organic matter into inorganic matter.

    In the most layman's terms, you can understand.

A complete ecosystem includes producers, consumers, decomposers, and the environment in which they live. The absence of that will paralyze the entire ecosystem, and the ecosystem is very complex, for example, there are often many kinds of organisms that decompose the same substance. If mosquitoes go extinct, then in a short period of time, the ecosystem will be hit hard Therefore, the extinction of mosquitoes will have a big impact on the ecosystem, not just mosquitoes, the extinction of any kind of organism, even those that we don't seem to have much role in nature, will have a big impact on the ecosystem. >>>More
