Here’s a breakdown of why:

The stages described—starting from bare rock and gradually progressing through different types of vegetation (lichens, small annual plants, grasses, shrubs, and eventually trees)—are typical of primary succession.

2.Secondary succession occurs in areas that previously supported life but were disturbed or damaged, such as abandoned agricultural fields or areas after a forest fire. In secondary succession, ...
