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, and begins with pioneer species like lichens and mosses.

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 human activity.

Front

What role do pioneer species play in succession?

Back

Pioneer species, such as lichens and mosses, are the first organisms to colonize barren environments, helping to create soil and conditions for other species to thrive.

Front

How do lichens contribute to primary succession?

Back

Lichens begin to break down rock to form soil.

Front

What is a disturbance in ecological terms?

Back

A disturbance is an event that significantly alters the structure of an ecosystem, such as a natural disaster, human activity, or disease.

Front

What is an example of primary succession?

Back

An example of primary succession is the colonization of bare rock 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

What type of succession occurs after a natural disaster?

Back

Secondary succession occurs after a natural disaster wipes out most of the vegetation in a habitat.

Front

What type of soil is associated with primary succession?

Back

Primary succession occurs in areas with no soil.
