Question 13 • CA-Life Science B (High School)

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?

Answer
A
primary succession
B
secondary succession
C
a climax community
D
species extinction

Explanation

Secondary succession occurs when an ecosystem regrows after a disturbance that removes vegetation but leaves the soil intact. Since the Yellowstone fires destroyed most plants while leaving the soil, the ecosystem underwent secondary succession. Primary succession begins where soil is absent, such as on bare rock.
