1. Primary succession is the change in the structure of an ecosystem represented with the increase of the ecological community on an area that has not been previously occupied by an ecological community such as area after the lava flow or glacial lake.

2. Secondary succession includes the step of removal of pre-existing community and after that, colonization of the new one.
