What is the value of the richness of the species composition of the biogeocenosis?

Communities with poor species composition are unstable. The species present in them do not form a single cycle of substances that maintain the stability of the biogeocenosis, since there are often no trophic connections between species and the loss of some link in its structure is observed.
