When does secondary succession occur?

Answer 1

Secondary succession occurs when there has been some type of disruption in a habitat. There must already be something living there.

The predictable pattern of how organisms live in a given area is called succession. Primary succession occurs when there has never been life there, such as on a newly formed island due to volcanic eruptions, while secondary succession happens when there has been life previously, such as when a fire burns a portion of a forest.

Secondary succession occurs after a disturbance, such as a fire or human activity, disrupts an existing ecosystem but leaves the soil intact.
