Prove that the cycle of substances in the ecosystem is the result of the interaction of producers, consumers and reducers.

Living organisms participate in the movement of substances, so the circulation of substances is biogenic. Producers synthesize organic substances, some of which are passed on to the consumers along the food chain, and some remain unused. A certain amount of organic matter of producers and consumers is returned to the soil with cadaveric material, excrement (detritus). As a result of the activity of reducers, they turn into minerals, involved by producers in a new cycle.
