Ecological 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 the two main types of ecological succession?

Back

Primary succession and secondary succession.

Front

What is primary succession?

Back

Primary succession occurs in an area where there is no soil, such as after a volcanic eruption or glacier retreat.

Front

What is secondary succession?

Back

Secondary succession occurs in areas where soil is present but the ecosystem has been disturbed, such as after a forest fire.

Front

What is a 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 the final, stable stage of ecological succession, characterized by a diverse and mature ecosystem.

Front

What role do disturbances play in ecological succession?

Back

Disturbances, like fires or floods, can reset succession stages and create opportunities for new species to establish.

Front

What is the difference between a pioneer community and a climax community?

Back

A pioneer community consists of the first species to inhabit an area, while a climax community is a mature, stable ecosystem.

Front

How does soil affect primary and secondary succession?

Back

Primary succession begins without soil, while secondary succession begins in areas where soil is already present.

Front

What is an example of a disturbance that can benefit an ecosystem?

Back

Fire can be beneficial as it clears out old vegetation, allowing new growth and increasing biodiversity.
