Question

which statement best describes ecological succession?
it is always caused by human intervention.
it occurs after a disturbance.
it never occurs in a predictable pattern.
it is a series of rapid changes in an ecosystem.

Explanation:

Ecological succession is the predictable, gradual change in an ecosystem's community structure over time. It can be initiated by natural disturbances (like wildfires or volcanic eruptions) or human activity, but is not always caused by humans. It follows a predictable pattern and occurs slowly, not rapidly. The only accurate statement is that it occurs after a disturbance.

Answer:

It occurs after a disturbance.
