Question

2 multiple choice 1 point secondary succession differs from primary succession because: it starts on bare rock it starts where soil already exists it begins after volcanic activity it produces lower biodiversity

Explanation:

Primary succession occurs in lifeless areas where soil has not yet formed (e.g., bare rock after volcanic activity). Secondary succession happens in areas where a disturbance (like a fire) has destroyed an existing ecosystem but left the soil intact. Biodiversity can increase in both successions.

Answer:

It starts where soil already exists.
