Explanation

Whole living matter is made up of nutrients, either as structural components, biochemical as enzymes. An ecosystem has a limited supply of biogenetic nutrients in its abiotic environment. They are picked by producers and made part of organic matter. From producers the nutrients in the form of organic matter pass to the higher trophic level. They are released back to abiotic environment by decomposers acting on organic wastes and dead bodies of organisms. Thus, if decomposers get vanish nutrients stop to repeatedly exchange between biotic and abiotic components of biosphere.
