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 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 community but left the soil intact, such as after a forest fire.

Front

What are pioneer species?

Back

Pioneer species are the first organisms to colonize previously uninhabited or disturbed environments, playing a crucial role in soil formation.

Front

Give an example of a pioneer species.

Back

Lichens and mosses are common examples of pioneer species that help create soil in primary succession.

Front

What is the role of pioneer species in succession?

Back

Pioneer species help create soil and add nutrients to the environment, facilitating the establishment of other species.

Front

What is the difference between primary and secondary succession regarding soil?

Back

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

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 succession?

Back

Factors influencing succession include climate, soil type, availability of species, and disturbances.
