What happens to climax communities after a disruption? How do these communities re-establish themselves after a disruption like a tropical storm? What is this process called?
· Succession is the process in which a disrupted climax community is re-established.
· The disruption makes the environment hostile and unsuitable for original species of the community. The destruction of the original community opens up the habitat and the niches within it to other species.
· A few tolerant species move into the area once the original community is gone. These initial species then draw in other species that depend on them.
· Eventually the climax community will return to the area. New climax communities develop when the disruption forever alters the environment.
