Front

What type of ecological succession occurs when a glacier melts and exposes bare rock?

Back

Front

What type of succession is characterized by the recovery of an ecosystem after a disturbance, such as a forest fire?

Front

What is the first species you will see in the early stages of primary succession?

Back

Lichens are typically the first species.

Front

What is a climax community?

Back

A climax community is a stable and mature ecological community that has reached a steady state.

Front

What role do lichens play in primary succession?

Back

Lichens help to break down rock and create soil, facilitating the growth of other plants.

Front

What is the difference between primary and secondary succession?

Back

Primary succession occurs in lifeless areas, while secondary succession occurs in areas where a disturbance has destroyed an existing community.

Front

Can you name an example of a disturbance that leads to secondary succession?

Back

Forest fires, floods, or human activities like farming can lead to secondary succession.

Front

What are some common pioneer species in secondary succession?

Back

Common pioneer species include grasses and small shrubs.

Front

How does soil development occur during primary succession?

Back

Soil develops as pioneer species die and decompose, adding organic matter.
