Succession

Succession is the gradual process of change in an ecosystem after it has been destroyed. The process of succession continues until it gets to a climax community. Some examples are when a forest burns down and it starts growing new bushes and trees. There are two types of succession. The first is called primary succession. Primary succession occurs in an area that is bare rock, or brand new. This is caused by a volcano eruption or new island forming. Primary succession starts with a pioneer species coming and starting up the succession process. The other kind of succession is secondary succession. Secondary succession happens when a forest is destroyed by flooding or fire and the forest begins to recover by growing new small plants, then bushes, then small trees, until it gets to a climax community.
