The question was posed to me in an interview for job.

I want to ask this question from Ecological Succession in division Ecosystems of Energy Management

Answer 1

Correct choice is (b) Secondary succession

To explain I would say: Secondary succession refers to the concept of an ecosystem reviving itself after all has been destroyed. In an area where a volcano erupts the lava inside cause damage to the plant and tree life. If the land which was affected by volcanic eruption and not covered in new volcanic rock, roots or plants parts in soil could renew.
