چکیده
Ecology can be defined as the study of ecological systems. A system is any set of components, living or nonliving, that are tied together by regular interactions.

An ecological system can be a single organism and its surroundings, a population or set of interacting populations in a certain habitat, or the entire community together with the abiotic environment with which these species interact, a unit termed an ecosystem.
