Similarities and differences (food chains, layering, energy consumption) of biocenosis and agrocenosis.

Biocenosis is a collection of plants, animals and microorganisms that live in one definite territory and enter into various relationships. Agrocenosis is an artificial biocenosis created by man. The food chains in the natural biocenosis branch and intertwine; there are even third-order consumers here. In trophic terms, the biocenosis is more diverse and richer than the agrocenosis, where only one species often predominates. There are no consumables, parasites and decomposers in the agrocenosis, that is, the trophic chain is disrupted. Since in most agricultural crops there is only one type of organisms, then there can be no question of any tiering – there are only 1-2 tiers. In the biocenosis, the tiering is more developed: the number of tiers can be 3-7 (and even more). The agrocenosis has more energy costs – it constantly requires a new “portion” of energy in the form of fertilizers and depends on the person. The biocenosis is independent and balanced in this regard.
