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 are the two main types of ecological succession?

Back

The two main types of ecological succession are primary succession and secondary succession.

Front

What is primary succession?

Back

Primary succession occurs in lifeless areas where soil has not yet formed, such as after a volcanic eruption or glacier retreat.

Front

What is secondary succession?

Back

Secondary succession occurs in areas where a disturbance has destroyed an existing ecosystem but left the soil intact, such as after a forest fire or land clearing.

Front

What is a climax community?

Back

A climax community is a stable and mature ecosystem that has reached the final stage of succession, characterized by high biodiversity.

Front

What role do pioneer species play in succession?

Back

Pioneer species are the first organisms to colonize barren environments, helping to create soil and conditions for other species to thrive.

Front

What is the significance of soil in primary succession?

Back

Soil is essential in primary succession as it provides nutrients and a substrate for plants to grow, which is not present initially.

Front

How does a tornado affect an ecosystem?

Back

A tornado can disrupt an ecosystem by uprooting trees and destroying habitats, leading to the beginning of secondary succession.

Front

What is an example of a disturbance that can lead to secondary succession?

Back

An example of a disturbance that can lead to secondary succession is a forest fire that clears vegetation but leaves the soil intact.

Front

What is the difference between primary and secondary succession?

Back

The main difference is that primary succession starts on bare rock or lifeless areas without soil, while secondary succession occurs in areas where soil is already present.
