Ecological Succession Test

Front

What is ecological succession?

Back

Ecological succession is the process by which ecosystems change and develop over time, involving a series of stages that lead to a stable community.

Front

What is primary succession?

Back

Primary succession is the type of ecological succession 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 type of ecological succession that occurs in an area where soil is already present, typically after a disturbance like a fire or flood.

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 is a climax community?

Back

A climax community is a stable and mature ecological community that has reached the final stage of succession.

Front

What role do abiotic factors play in succession?

Back

Abiotic factors, such as soil, water, and climate, influence the types of organisms that can thrive in an ecosystem during succession.

Front

How does soil formation occur in primary succession?

Back

In primary succession, soil formation occurs as pioneer species break down rock and organic matter accumulates over time.

Front

What is the difference between primary and secondary succession?

Back

Primary succession starts from bare rock with no soil, while secondary succession begins in areas where soil is already present.

Front

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

Back

An example of an event that triggers secondary succession is a forest fire that clears vegetation but leaves the soil intact.

Front

What is the significance of lichens in primary succession?

Back

Lichens are significant in primary succession as they can grow on bare rock, helping to break it down and contribute to soil formation.
