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 or logging.

Front

What is a pioneer species?

Back

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

Front

Give an example of primary succession.

Back

An example of primary succession is the formation of a new island from volcanic activity, where life begins to establish on bare rock.

Front

Give an example of secondary succession.

Back

An example of secondary succession is the regrowth of a forest after a wildfire, where the soil and some plant life remain.

Front

What role do disturbances play in ecological succession?

Back

Disturbances, such as fires, floods, or human activities, can reset ecological succession, allowing new species to establish and change the community structure.

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, characterized by a diverse and balanced ecosystem.

Front

How does soil development occur in primary succession?

Back

In primary succession, soil development occurs as pioneer species break down rock and organic matter accumulates, creating a substrate for other plants.

Front

What factors influence the rate of succession?

Back

Factors influencing the rate of succession include the type of disturbance, climate, soil quality, and the availability of species for colonization.
