An ecosystem, especially a food web, is essentially characterized as a manybody system in which the members interact with each other under the limitations of the energy and resources. The study of complex adaptive systems has fascinated natural and social scientists from across a tremendous range of disciplines. Selforganization, also called in the social sciences spontaneous order, is a process where some form of overall order arises from local interactions between parts of an initially disordered system. An ecosystem is a community of living and nonliving things that work together it consists of abiotic soil, water, air and biotic parts flora, fauna.
