Ecosystem
An ecosystem is a community made up of living organisms and nonliving components such as air, water, and mineral soil. Ecosystems may be studied either as contingent collections of plants and animals, or as structured systems and communities that are governed by general rules. The biotic and abiotic components interact through nutrient cycles and energy flows. Ecosystems include a network of interactions among organisms, and between organisms and their environment. Ecosystems can be of any size but one ecosystem has a specific, limited space. Some scientists view the entire planet as one ecosystem.
Ecosystem
The organization of life extends beyond the individual organism to the biosphere, the zone of air, land, and water at the surface of the Earth where organisms exist. Individual organisms belong to a population, which is all the members of a species within a particular area. The populations of a community interact among themselves and with the physical environment (e.g., soil, atmosphere, and chemicals), thereby forming an ecosystem.

Ecosystem
If we recognise that every ecosystem can also be viewed as a food web, we can think of it as a circular, interlacing nexus of plant animal relationships (rather than a stratified pyramid with man at the apex)... Each species, be it a form of bacteria or deer, is knitted together in a network of interdependence, however indirect the links may be.
Murray Bookchin, The Ecology of Freedom (1982).
Ecosystem
Ecosystems are characterized by chemical cycling and energy flow, both of which begin when photosynthetic plants, aquatic algae, and some bacteria take in solar energy and inorganic nutrients to produce food in the form of organic nutrients.
