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.

What is primary succession?

Back

Primary succession occurs in an area where no soil exists, such as after a volcanic eruption or glacier retreat, starting from bare rock.

Front

What is secondary succession?

Back

Secondary succession occurs in areas where a disturbance has destroyed an existing ecosystem 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 land, such as lichens and mosses in primary succession.

Front

What is the role of lichens in primary succession?

Back

Lichens help break down bare rock into soil, making it possible for other plants to grow in primary succession.

Front

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

Back

Lichens → Grasses → Shrubs → Trees.

Front

What is the difference between primary and secondary succession?

Back

Primary succession starts from bare rock with no soil, while secondary succession begins in areas where soil is present after a disturbance.

Front

What type of succession occurs after a forest fire?

Back

Secondary succession occurs after a forest fire.

Front

What is an example of an event that leads to primary succession?

Back

A newly formed volcanic island is an example of an event that leads to primary succession.

Front

What is a climax community?

Back

A climax community is a stable and mature ecological community that has reached a steady state through the process of succession.
