Explanation:

Succession is the process of change in the species structure of an ecological community over time. Human activity can interrupt this natural process. Mowing a lawn is a human - induced action that destroys the regrowth of plants, thus interrupting the natural succession of the lawn's plant community. A volcanic eruption is a natural event, and lichens and moss creating soil from rock is a part of natural primary succession.

mowing a lawn destroying the regrowth
