A climax community is mature, self-sustaining, and stable and is the final stage of succession the physical and chemical conditions are altered and stabilized to such levels that it supports the entire community. Such an orderly and progressive replacement tot one community by another until a relatively stable community, called the climax community, occupies the area is called ecosystem development or ecological succession.
