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 an area during succession, often including lichens and mosses.

Front

What is the role of pioneer species in succession?

Back

Pioneer species help to create soil and conditions that allow other species to establish, facilitating the process of succession.

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 a volcanic eruption affect ecological succession?

Back

A volcanic eruption can create new land, initiating primary succession as organisms colonize the barren landscape.

Front

What is the order of plant growth after a volcanic eruption?

Back

The order of plant growth after a volcanic eruption is typically: Lichens → Grasses → Shrubs → Trees.

Front

What is the difference between primary and secondary succession?

Back

Primary succession starts on bare rock without soil, while secondary succession occurs in areas where soil is already present after a disturbance.
