Explanation:

Ecological succession, which is the series of changes that occurs in an ecosystem over a period of time, can be divided into two types namely: primary succession and secondary succession.

- Primary succession is a kind of succession in which a bare surface or rock is colonized by certain organisms called PIONEERS. Primary succession occurs in an area with no life and no previous soil.

- On the contrary, secondary succession occurs in an area that has been previously colonized but disturbed as a result of natural occurrences e.g earthquake, wildfire, flooding etc.
