Succession

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 pioneer species?

Back

Pioneer species are the first organisms to colonize a barren environment during the initial stages of ecological 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.

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

How does biodiversity change during succession?

Back

Biodiversity typically increases during succession as more species colonize the area and establish themselves.

Front

Why are ecosystems with high biodiversity more resilient?

Back

Ecosystems with high biodiversity are more resilient because they have a greater variety of species that can adapt to changes and disturbances.

Front

What role do intermediate species play in succession?

Back

Intermediate species are those that establish themselves after pioneer species and contribute to the development of a more complex ecosystem.

Front

What is the difference between primary and secondary succession?

Back

Primary succession starts on bare rock or lifeless areas, while secondary succession occurs in areas where an ecosystem has been disturbed but soil remains.

Front

What factors can influence the rate of succession?

Back

Factors influencing succession include climate, soil type, availability of species, and the nature of the disturbance.
