Ecological Succession

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 ecosystem but left the soil intact, such as after a forest fire or human activity.

Front

What are pioneer species?

Back

Pioneer species are the first organisms to colonize previously uninhabited or disturbed land, often leading to the establishment of a new ecosystem.

Front

Give an example of a pioneer species.

Back

Lichens and mosses are common examples of pioneer species that can grow on bare rock.

Front

What role do grasses play in ecological succession?

Back

Grasses are often among the first plants to return after a disturbance, playing a crucial role in stabilizing the soil and providing habitat.

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.

Front

How do natural disasters affect ecological succession?

Back

Natural disasters can trigger secondary succession by creating disturbances that clear existing vegetation and allow new species to establish.

Front

What is the significance of lichen in primary succession?

Back

Lichen helps in soil formation by breaking down rock and contributing organic material, paving the way for other plants.
