Environmental Science 2nd Benchmark Review 24.25

Front

What are pioneer species in primary succession?

Back

Pioneer species are the first organisms to colonize barren environments, such as mosses and lichens, which help in soil formation.

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 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.

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.

Front

What is a climax community?

Back

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

Front

Give an example of a pioneer species.

Back

Mosses and lichens are examples of pioneer species.

Front

What type of succession occurs after a forest fire?

Back

Secondary succession occurs after a forest fire.

Front

What is the role of pioneer species in succession?

Back

Pioneer species help to create soil and establish conditions for other species to thrive.

Front

What happens to biodiversity during primary succession?

Back

Biodiversity gradually increases as more species colonize the area over time.

Front

How does soil affect the rate of succession?

Back

Soil presence accelerates succession, allowing for a quicker establishment of plant and animal communities.
