Question

Which is true of secondary succession? A. It happens after new land is uncovered. B. It begins on nonliving rock and land. C. It occurs in land and marine communities. D. It takes place on land that had no life.

Answer 1

The correct answer is option C

In a secondary succession life is recreated after the land has been wiped of all earlier life forms or a destructive event had taken place in past which had destroyed all life forms on that particular land. So creation or generation of life on such land again is called secondary succession. This is the case which can occur only in option C where land and marine system can be developed to posses life after a certain destruction or clearance.

Answer 2

I think it is C, since it does occur on land life, and I think it also occurs in marine life.
