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.
The tissues are made of different types of cells. The organs are also made of different types of tissue. There is no need of same types of tissues to make organs. Thus, option (B) and (D) is correct answer.

I'd say that it is incorrect because each carbon atom should bond 4 times and all three carbon atoms in this structural formula only bond once. The reverse is true for hydrogen atoms. They only form one bond but in this structural formula two of them have four bonds. I don't know about nitrogen though.
