Ecological Succession Review

What is ecological succession?

Back

Ecological 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 ecological 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 community 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 is a climax community?

Back

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

Front

What role do lichens play in primary succession?

Back

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

Front

What is the difference between primary and secondary succession?

Back

Primary succession begins without soil, while secondary succession begins with soil.

Front

What is soil formation in primary succession?

Back

Soil formation is a crucial step in primary succession, allowing for the growth of more complex plant species.

Front

What is an example of a pioneer species?

Back

An example of a pioneer species is lichen, which can grow on bare rock.
