What is the difference between primary and secondary succession?

Back

Primary succession occurs in lifeless areas without soil, while secondary succession occurs in areas where a disturbance has destroyed an existing ecosystem but soil remains.

Front

Can a forest fire lead to primary succession?

Back

False. A forest fire leads to secondary succession because soil and some organisms remain.

Front

What role do pioneer species play in primary succession?

Back

Pioneer species help to create soil by breaking down rock and adding organic material as they die and decompose.
