What groups represent the species structure of the biocenosis?

– dominant species – medium-forming (mass species). These species determine the main connections in the community, its microclimate, structure, and characteristic appearance. For example, in European taiga forests, the spruce is formed by European spruce. In old spruce forests, tree crowns absorb so much light that neither other trees nor shrubs grow below. Fallen needles acidify the soil during decomposition and inhibit the growth of many plant species. The life of most animals of the community is associated with this species – from small arthropods to birds and mammals eating spruce seeds.
