Question

Primary succession would begin after

a hay field is mowed.

a timber plot is harvested.

a vegetable garden is abandoned.

a volcano erupts.

Answer 1

Primary succession typically begins in an area where no soil exists, such as after a catastrophic event that removes all life and soil. Among the options provided, **a volcano erupts** is the correct answer, as it can create new land by lava flows and ash, leaving behind a barren landscape where primary succession can occur.

In contrast, the other options involve situations where soil already exists – after a hay field is mowed, a timber plot is harvested, or a vegetable garden is abandoned – leading to secondary succession instead.
