What is primary succession?

Back

A type of ecological succession that 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

A type of ecological succession that occurs in areas where a disturbance has destroyed an existing community but left the soil intact, such as after a forest fire.

Front

What are pioneer species?

Back

The first species to colonize previously disrupted or damaged ecosystems, often including lichens and mosses.

Front

What is a climax community?

Back

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

What role do lichens play in primary succession?

Back

Lichens help break down rocks into soil, making it possible for other plants to grow.

Front

What is an ecosystem?

Back

A community of living organisms and their interactions with their physical environment.

Front

How does succession increase biodiversity?

Back

As succession progresses, more species are introduced, leading to a greater variety of organisms in the ecosystem.

Front

What is an example of an area undergoing primary succession?

Back

An area exposed by a melting glacier.

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.
