Name the main natural regularities that ensure the preservation of the stability of biogeocenoses.

Biogeocenosis is a certain area with approximately the same environmental conditions (climate, humidity, atmospheric pressure, etc.) where various living organisms live. These are animals, plants, fungi and microorganisms. The stability of biogeocenoses depends on the number of species and on the number of food chains in which these species are located. If one species in the food chain can be replaced by another in a given biogeocenosis, this makes it more stable. Then the disappearance of one or some species will not be able to destroy the entire system.
