Front

What is secondary succession?

Back

Secondary succession is the process of ecological change that occurs in an area where soil is present but has been disturbed, such as after a forest fire or human activity.

Front

What are pioneer species?

Back

Pioneer species are the first organisms to colonize a barren environment in the process of succession, such as lichens and mosses.

Front

How does primary succession differ from secondary succession in terms of time?

Back

Primary succession takes more time than secondary succession because it starts from bare rock and requires soil formation.

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

Which organisms are typically NOT considered pioneer species?

Back

Shrubs are typically NOT considered pioneer species; pioneer species include lichens, mosses, and fungi.

Front

What role do pioneer species play in succession?

Back

Pioneer species help to create soil and modify the environment, making it suitable for other species to inhabit.

Front

What is the first stage of primary succession?

Back

The first stage of primary succession is the colonization of bare rock by pioneer species.

Front

What is the significance of soil in secondary succession?

Back

Soil is significant in secondary succession because it allows for faster recovery and regrowth of plant life compared to primary succession.
