The ecosystem is the set of living organisms and the environment in which they live, the relationship between these two components forms a system that must be fair to be in balance.
Each ecosystem is made up of one or more communities of living (biotic) organisms and non-living (abiotic) elements that interact with each other; a community is itself the set of several populations.
This concept was introduced in 1935 by the English ecologist AG Tansley, taking into account the complex interactions between organisms (e.g. plants, animals, bacteria, protists and fungi) that form the community and the flows of energy and materials that pass through it.
This term is widely used when referring to sustainability and eco-sustainability issues, for which it should be taken into account; A product or service that claims to be eco-friendly is telling us that it is minimally or non-invasive with this system in balance.
