Ecological Succession

Front

What are pioneer species?

Back

Pioneer species are the first organisms to reappear in an ecosystem after it has been damaged, often colonizing barren environments.

What is ecological succession?

Back

Ecological succession is the process by which ecosystems change and develop over time, involving a series of stages from bare ground to a stable community.

Front

What is primary succession?

Back

Primary succession occurs in an area that has no soil, 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.

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

What is an example of primary succession?

Back

An example of primary succession is when glaciers melt and leave exposed rock, allowing new life to establish.

Front

What is an example of secondary succession?

Back

An example of secondary succession is when a forest regrows after a fire, starting with grasses and shrubs.

Front

What role do lichens play in succession?

Back

Lichens are often the first organisms to colonize bare rock in primary succession, helping to create soil.

Front

What is the difference between primary and secondary succession?

Back

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

Front

What is a disturbance in an ecosystem?

Back

A disturbance is an event that disrupts the structure or function of an ecosystem, such as fire, flood, or human activity.
