An ecosystem is composed of communities of living organisms at aparticular time. This includes plants and animals, as well asnon-living elements such as water, wind, heat, chemicalconstituents, etc. Each organism within a community has a habitatand a niche (Figure 1). An organismâs habitatisthe location in which it physically resides or is adapted toreside. An organismâs niche refers its function orâoccupationâ. Occupation defines the way in which the organismobtains and sustains all of the elements needed for survival.
