Ecological Succession Review

Front

What are pioneer species?

Back

Pioneer species are the first organisms to colonize previously disrupted or damaged ecosystems, initiating the ecological succession process.

Front

Which of the following is NOT a pioneer species?

Back

Shrubs are not considered pioneer species.

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 the ecosystem has been disturbed, such as after a forest fire.

Front

What is formed during primary succession that doesn't need to be formed during secondary succession?

Back

Soil is formed during primary succession.

Front

What is the main difference between primary and secondary ecological succession?

Back

Primary succession begins without soil, while secondary succession begins with soil.

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

What role do lichens play in primary succession?

Back

Lichens are often the first organisms to colonize bare rock, helping to break it down and contribute to soil formation.

Front

How does fire influence ecological succession?

Back

Fire can trigger secondary succession by clearing out existing vegetation and allowing new growth to occur.

Front

What is the significance of biodiversity in a climax community?

Back

Biodiversity in a climax community contributes to ecosystem stability and resilience.
