Succession

What is succession?

Back

Succession is the process by which ecosystems change and develop over time, involving a series of stages that lead to a stable community.

Front

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 or glacier retreat.

Front

What is secondary succession?

Back

Secondary succession occurs in areas where a disturbance has destroyed an existing ecosystem but left the soil intact, such as after a forest fire.

Front

What are pioneer species?

Back

Pioneer species are the first organisms to colonize barren environments during primary succession, such as lichens and mosses.

Front

What role do pioneer species play in succession?

Back

Pioneer species help to create soil by breaking down rock and accumulating organic matter, paving the way for other species.

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 soil formation differ between primary and secondary succession?

Back

Soil is formed during primary succession from bare rock, while in secondary succession, the existing soil remains intact.

Front

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

Back

Natural disasters such as floods, fires, or tornadoes can lead to secondary succession.

Front

What is the significance of a glacier retreating in terms of succession?

Back

Glacier retreat exposes bare rock, initiating primary succession as new ecosystems begin to form.
