Question

What is the difference between primary ecological succession and secondary ecological succession?

Answer 1

1] Primary succession occurs in esentially lifeless areas or regions in which the soil is incapable of sustaining life.

Examples of primary ecological succession are lava flows, newly formed sand dunes or rocks left from retreating glacier.

2] Secondary ecological succession occurs in areas where a community that previously existed has been removed. It is typified by smaller scale disturbances that do not eliminate all life and nutrients from the environment.

Examples of secondary ecological succession are forest fire, tsunami, flood or an abandoned field.
