The correct answer is (C) competition which determines the succession of an animal in the ecosystem.
<h3>
What factors influence when an animal species enters a successional ecosystem?</h3>
Interaction and competition among species in a certain environment is a biotic element of ecological primary succession. When succession begins and the first species, known as pioneer species, alter the environmental structure, new species that are more tolerant of the new conditions move in.
These communities gradually replace one another until a "climax community"—such as a mature forest—is attained or a disturbance, such as a fire, occurs.
