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 community but left the soil intact, such as after a forest fire or human activity.

Front

Which type of succession is generally faster?

Back

Secondary Succession is generally faster than Primary Succession.

Front

What is a climax community?

Back

A climax community is a stable, mature ecological community that has reached the final stage of succession.

Front

What is an example of a disturbance that can lead to Secondary Succession?

Back

Humans cutting down many trees in a small region.

Front

What is an example of an area likely to undergo Primary Succession?

Back

An area where glaciers have melted and left exposed rock.

Front

What is the first step in Primary Succession?

Back

The colonization of bare rock by pioneer species such as lichens and mosses.

Front

What role do pioneer species play in Primary Succession?

Back

Pioneer species help to create soil by breaking down rock and accumulating organic matter.
