Question

Plants colonizing bare rock after a volcanic eruption denudes the area are an example of primary succession.

Quizplus · Accepted Answer

Primary succession occurs when an area is completely denuded of all life and soil, such as after a volcanic eruption. The first organisms to colonize the area are usually pioneer plants such as mosses and lichens that can grow directly on bare rock. As these pioneer species die and decompose, they create the beginnings of soil and nutrients that can eventually support more complex plant life.
