Succession

Front

What is primary succession?

Back

Primary succession is the process of ecological change that occurs in an area where no soil exists, 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 soil is present but has been disturbed, such as after a forest fire or human activity.

Front

What are pioneer species?

Back

Pioneer species are the first organisms to colonize a barren environment in primary succession, such as lichens and mosses.

Front

What role do lichens play in primary succession?

Back

Lichens help to break down rock and contribute to soil formation, 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 formation differ between primary and secondary succession?

Back

Soil is formed during primary succession from bare rock, while in secondary succession, soil already exists and is often enriched by organic matter.

Front

What is the first type of vegetation to return after a forest fire?

Back

Grasses are typically the first plants to return after a forest fire.

Front

What is the significance of fire in forest ecosystems?

Back

Fire can stimulate new growth, recycle nutrients, and help maintain the health of certain ecosystems.

Front

What is an example of an event that triggers primary succession?

Back

The formation of a new island from volcanic activity is an example of an event that triggers primary succession.

Front

What is an example of an event that triggers secondary succession?

Back

A forest fire is an example of an event that triggers secondary succession.
