Answer 1

I think the correct answer from the choices listed above is option C. During an ecological succession of an ecosystem, what happens is that living organisms modify their environment a little at a time in order for them to survive. Hope this answers the question.

Answer 2

The answer is c. Living organisms modify their environment a little at a time.

The purpose of succession is for an ecosystem to reach balance state right after it is formed or after it is disturbed by man or some disasters. It will increase biodiversity and help to prevent the desertification. Living organisms modify environment a little at a time. By modifying it, they make the environment more suitable for the new species to enter the community.
