Ecological Succession (Primary and Secondary)

Front

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 climax community.

Front

What are the two main types of ecological succession?

Back

The two main types of ecological succession are 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 is a 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 is an example of primary succession?

Back

An example of primary succession is when glaciers melt and expose bare rock, allowing new life to establish.

Front

What is an example of secondary succession?

Back

An example of secondary succession is the regrowth of a forest after a wildfire.

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

How does a climax community differ from a pioneer community?

Back

A climax community is more complex and stable, while a pioneer community is the initial stage of succession with simple organisms.
