In nature, plants and animals decompose, or break down into their principal nutrients with the help of insects, bacteria, and other microorganisms. These decomposers play an extremely important role in nature and without them the Earth would be piled high with dead things. Microorganisms such as bacteria and fungi feed on dead plants and animals, helping them to decay. These microorganisms respire, releasing carbon dioxide back into the air. Mineral ions return to the soil through decay.

I will first answer this question with another question: Let us imagine that living organisms, including humans, animals, and plants, stopped life without any decomposition of the components and for a period of one year, for example. How will these structures stack on top of each other? What is the height above the surface of the earth’s crust that these structures will reach? And if it will happen after 10 years? The decomposition that occurs redistributes the compounds and components again in a simpler way to the soil and in a somewhat proportional distribution within the layers of the earth's crust, so that these components enter again in a new arrangement for new organisms, and so on, and this feature that makes decomposition one of the most important solutions in the survival of resources For the new configuration is available, but we say the sustainability of these sources.
