Front

What is the difference between primary and secondary succession?

Back

Primary succession begins without soil, while secondary succession begins with soil.

Front

What is an example of an area undergoing primary succession?

Back

An example is when glaciers melt and leave exposed rock.

Front

What is an example of an area undergoing secondary succession?

Back

An example is a forest recovering after a fire.

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 like lichens.

Front

What is the importance of soil in ecological succession?

Back

Soil provides nutrients and a habitat for plants and animals, facilitating the development of a stable community.
