Ecological Succession

Front

What is ecological succession?

Back

Ecological succession is the process by which ecosystems change and develop over time, involving a series of stages where different communities of plants and animals replace one another.

Front

What is primary succession?

Back

Primary succession occurs in an area where no soil exists, such as after a volcanic eruption, and begins with pioneer species like lichens and mosses.

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, such as after a forest fire.

Front

What are pioneer species?

Back

Pioneer species are the first organisms to colonize previously uninhabited land, such as lichens and mosses in primary succession.

Front

What is the order of plant growth in primary succession after a volcanic eruption?

Back

Lichens → Grasses → Shrubs → Trees.

Front

Which type of succession takes longer, primary or secondary?

Back

Primary succession takes longer than secondary succession.

Front

What role do lichens play in primary succession?

Back

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

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 quality change during succession?

Back

Soil quality improves over time as organic matter accumulates from decaying plants and animals, making it more suitable for diverse plant life.

Front

What is the difference between primary and secondary succession?

Back

Primary succession starts from bare rock with no soil, while secondary succession starts from soil that remains after a disturbance.
