Question

multiple choice 1 point
which of the following best represents secondary succession?
glacier retreat
lava cooling into rock
regrowth after a forest fire
formation of new volcanic islands

Explanation:

Secondary succession occurs in areas where a disturbance has destroyed an existing ecosystem but left the soil intact. A forest fire is such a disturbance. After a fire, the soil remains, and regrowth can occur. Glacier retreat, lava cooling into rock, and formation of new volcanic islands involve the creation of new land with no existing soil (primary succession).

Answer:

Regrowth after a forest fire
