which factor can cause secondary succession?\n○ clear cutting\n○ glacial melting\n○ competition\n○ predation

Brief Explanations:

Secondary succession occurs in an area where a disturbance has destroyed an existing community but left the soil intact. Clear - cutting removes most of the trees in a forest but the soil remains, allowing for secondary succession. Glacial melting is associated with primary succession as it creates new land with no existing soil. Competition and predation are ecological interactions that do not directly cause secondary succession.

Answer:

clear cutting
