Ecological succession

Front

What is ecological succession?

Back

The process by which ecosystems change and develop over time, involving a series of stages that lead to a stable climax community.

Front

What is primary succession?

Back

Succession that occurs in an area with no soil, such as after a volcanic eruption or glacier retreat.

Front

What is secondary succession?

Back

Succession that occurs in an area where soil is already present, typically after a disturbance like a fire or flood.

Front

What are pioneer species?

Back

The first organisms to colonize a barren environment in the process of succession, often including lichens and mosses.

Front

What role do pioneer species play in ecological succession?

Back

They help to create soil and conditions that allow other species to establish and grow.

Front

What is a climax community?

Back

A stable and mature ecological community that has reached the final stage of succession.

Front

How does soil affect the rate of succession?

Back

Areas with existing soil (secondary succession) typically reach a climax community faster than areas without soil (primary succession).

Front

Give an example of primary succession.

Back

The colonization of bare rock after a volcanic eruption.

Front

Give an example of secondary succession.

Back

The regrowth of a forest after a wildfire.

Front

What is the difference between primary and secondary succession?

Back

Primary succession starts with bare rock and no soil, while secondary succession starts with existing soil after a disturbance.
