What is succession in ecology?

Back

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 there is 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 or flood.

Front

What are pioneer species?

Back

Pioneer species are the first organisms to colonize barren environments in primary succession, such as lichens and mosses.

Front

What role do disturbances play in succession?

Back

Disturbances, such as fires or floods, can reset ecological succession, allowing for secondary succession to occur.

Front

What is an example of primary succession?

Back

An example of primary succession is the colonization of bare rock by lichens and mosses after a volcanic eruption.

Front

What is an example of secondary succession?

Back

An example of secondary succession is the regrowth of a forest after a wildfire.

Front

How does soil quality affect succession?

Back

Soil quality influences the types of plants that can grow, affecting the speed and direction of succession.

Front

What is a climax community?

Back

A climax community is a stable, mature ecosystem that undergoes little change in species composition.

Front

What is the difference between primary and secondary succession?

Back

Primary succession starts with no soil and occurs in lifeless areas, while secondary succession occurs in areas where soil is present after a disturbance.
