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.

Atomic Theory:</h2><h2>
Introduction</h2>
The atomic theory of Atoms Summed up is the idea that all matter is made of tiny particles that are imperceptible to the mortal eye; these particles are named Atoms
<h2>
Paragraph 1:</h2>
John Dalton was the first to consider that all matter was made of tiny particles known as atoms. He invented the idea that matter is formed of atoms varying in weight.
<h2>
Paragraph 2:</h2>
I created this model of the dissimilarities between three kinds of matter-- solids, liquids, and gases. The distance between atoms in each state tells us what type of matter we observe.
