Question

Which type of process occurred in the ecosystem that was affected by the 1988 fires in Yellowstone Park, which destroyed most of the vegetation but left the soil intact?
primary succession

Answer 1

Secondary succession.

Explanation: Secondary succession occurs when a disturbance removes vegetation but leaves the soil intact, allowing regrowth from seeds, roots, and soil organisms. Primary succession would be on newly formed substrate with no soil.
