6.2 Succession

Front

What is primary succession?

Back

Primary succession is the process of ecological change that occurs in an area with no soil, such as after a volcanic eruption or glacier retreat.

Front

What is secondary succession?

Back

Secondary succession is the process of ecological change that occurs in an area where a disturbance has destroyed an existing ecosystem but soil and some organisms still remain, such as after a forest fire.

Front

What is ecological succession?

Back

Ecological succession is the gradual process of change and replacement in the species composition of a given area over time.

Front

What are pioneer species?

Back

Pioneer species are the first organisms to colonize previously uninhabited or disturbed land, playing a crucial role in the process of succession.

Front

What is the difference between primary and secondary succession?

Back

Primary succession occurs in lifeless areas without soil, while secondary succession occurs in areas where an ecosystem has been disturbed but soil and some organisms still exist.

Front

What role do disturbances play in succession?

Back

Disturbances, such as fires or storms, can reset ecological succession, allowing new species to establish and change the ecosystem.

Front

What is a climax community?

Back

A climax community is a stable and mature ecological community that has reached a steady state through the process of succession.

Front

How does soil development occur during primary succession?

Back

Soil development during primary succession occurs as pioneer species break down rock and organic matter accumulates, gradually creating soil.

Front

What is an example of primary succession?

Back

An example of primary succession is the formation of a new ecosystem on a lava flow after a volcanic eruption.

Front

What is an example of secondary succession?

Back

An example of secondary succession is the regrowth of a forest after it has been cleared by a wildfire.
