Biocenosis (from bio. And Greek. Koinos – common) (cenosis), a set of plants, animals and microorganisms that inhabit a given land or water body and are characterized by certain relationships between themselves and their adaptability to environmental conditions (e.g., biocenosis of a lake, forest) . Ecosystem (from the Greek. Oikos – home, location and system), a single natural complex formed by living organisms and their environment (atmosphere, soil, water, etc.), in which living and inert components are interconnected by the exchange of matter and energy. The concept of an ecosystem applies to natural objects of varying complexity and size: the ocean or a small pond, taiga or a section of a birch grove. The term “ecosystem” was introduced by the English phytocenologist A. Tensley (A. Tansley, 1935). Often the terms “ecosystem” and “biogeocenosis” are used as synonyms.
