List the required components of the biogeocenosis.

Biogeocenosis consists of several essential components. First of all, it is a certain area with relatively similar natural conditions. Also, biogeocenosis cannot exist without living organisms. This territory should be inhabited by various types of plants, fungi, animals and other organisms. All of them must be connected to each other in food chains. If there are no food chains, then such a biogeocenosis will be unstable. The more food chains with one species, the more stable such a biogeocenosis.
