Biogeocenosis is a complex of interconnected species (populations of different species) that live in a certain territory with more or less uniform conditions of existence.
Biogeocenosis is an integral self-regulating and self-sustaining system. It includes the following required components:
1) climatic conditions, inorganic (oxygen, nitrogen, carbon dioxide, water, mineral salts) and organic (proteins, carbohydrates, lipids, etc.) substances, i.e., inanimate nature;
2) autotrophic organisms – producers of organic substances;
3) heterotrophic organisms – consumers of finished organic substances of plant (first-order consumers) and animal (consumers of the second and next orders) origin; heterotrophic organisms also include destroyers – destructors, which decompose the remains of dead plants and animals, turning them into simple mineral compounds.
