A community An ecosystem is a collection of all the organisms that live in a particular area along with their nonliving, physical environment.Abiotic— An ecosystem has a set of environmental or non-living factors that define what will live there. These are called abiotic factors. For example: water, temperature, light, air, soil type, topography.
