What are the two main types of succession?

Back

Primary succession and secondary succession.

Front

What is primary succession?

Back

Primary succession occurs in lifeless areas where soil has not yet formed, such as after a volcanic eruption.

Front

What is secondary succession?

Back

Secondary succession occurs in areas where a disturbance has destroyed an existing ecosystem but soil and some organisms still remain.

Front

What are pioneer species?

Back

Pioneer species are the first organisms to colonize previously uninhabited land, playing a crucial role in primary succession.

Front

What role do lichens play in succession?

Back

Lichens are often pioneer species that help break down rock to form soil in primary succession.

Front

What is a climax community?

Back

A climax community is a stable and mature ecological community that has reached the final stage of succession.

Front

How does a forest fire affect succession?

Back

A forest fire can lead to secondary succession, where the ecosystem regrows after the disturbance.

Front

What is the difference between primary and secondary succession?

Back

Primary succession starts on bare rock without soil, while secondary succession occurs in areas where soil is already present.

Front

What is an example of a disturbance that can lead to secondary succession?

Back

Examples include forest fires, floods, and human activities like farming.
