The answer is <span>c. Living organisms modify their environment a little at a time.</span>
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.
Plants are very crucial for maintenance of balance of ecosytem as part of the equilibrium and the primary basis for the ecosystem as the producers.
Explanation:
The ecosystem consists of plants with animals and the environment surrounding it. The balance of all three elements is essential for the co existence of the ecosystem. devoid of any or excess of either factor will lead to destruction.
The imbalance so caused will lead to over production or over consumption of the strata in the ecosystem. Plants holds the producer level of the ecosystem which forms the basis to all, if dis-balanced all the factors relying on it will decline eventually and the world will fall.
The correct answer would be phenotypic variation.
