Question

Quizplus · Accepted Answer

Floods that remove organic matter on the surface of rocks and gaps observed in forests both create opportunities for early-succession species to colonize. In the case of floods, the removal of organic matter exposes bare rock which can be colonized by pioneer species. In the case of gaps in forests, the increased light and resources also create opportunities for early-succession species. Both events can play a role in the overall succession of an ecosystem.
