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?

What are pioneer species?

Back

Pioneer species are the first organisms to colonize an area during ecological succession, often including lichens and mosses.

Front

What happens to species diversity during succession?

Back

As ecological succession progresses, the number of species typically increases, leading to greater biodiversity.

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 soil development occur in primary succession?

Back

In primary succession, soil develops gradually as pioneer species break down rock and organic matter accumulates.

Front

What role do disturbances play in ecological succession?

Back

Disturbances, such as fires or storms, can reset succession, leading to secondary succession in previously established ecosystems.

Front

What is the difference between primary and secondary succession?

Back

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

Front

Can ecological succession occur in aquatic environments?

Back

Yes, ecological succession can occur in aquatic environments, such as ponds and lakes, where changes in water levels and vegetation can lead to succession.
