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 progressive changes in species composition and community structure.

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 soil and some organisms still remain, such as after a forest fire.

Front

What are pioneer species?

Back

Pioneer species are the first organisms to colonize a barren environment in primary succession, such as mosses and lichens.

Front

What is the main difference between primary and secondary succession?

Back

Primary succession begins without soil, while secondary succession begins with soil.

Front

What role do pioneer species play in primary succession?

Back

Pioneer species help to create soil by breaking down rock and accumulating organic matter, paving the way for other species.

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 factors can influence the rate of ecological succession?

Back

Factors include the type of disturbance, climate, soil quality, and the availability of species.

Front

What is the order of succession in a typical forest ecosystem?

Back

The order is usually: pioneer species -> intermediate species -> climax community.

Front

How does human activity affect ecological succession?

Back

Human activities, such as deforestation and urbanization, can disrupt natural succession processes and lead to altered ecosystems.
