ecosystem

An ecosystem comes down to the association of two components in constant interaction with each other: an environment (biotope) and a living community (biocenosis). The elements which make up an ecosystem develop a network of energy and matter exchange, enabling the maintenance and development of life. The different seas, mountains, deserts or forests are ecosystems.
