The structure of the biocenosis is maintained in time and space due to the diverse relationships between populations. Four types of connections are distinguished depending on the nature of needs: trophic, topical, foric, and Fabri. Trophic connections are connections between populations when individuals of one population receive food at the expense of individuals of another population. Topical connections are relations between populations when individuals of one population use individuals of another population as a habitat or experience their influence on their habitat. Foricheskie communication – communication between populations, when individuals of one population participate in the distribution (distribution) of individuals of another population. Fabric relations are relations between populations when individuals of one population use excreta or dead parts of the bodies of individuals of another population as material for building nests, burrows, shelters, etc. and they sprout in the spring.
