tropism succession gradualism eutrophication
I gave my students this multiple choice question: Fires in forests from lightning rid the forest of dead branches and leaves. If the trees survive and the soil remains intact, the forest will experience regrowth to its climax state by which process?

Only one answer is correct among these 4 choices:
- tropism
- succession
- gradualism
- eutrophication

Could you tell me which one is correct?

succession
