A. To build structure made of protein and make genetic molecules (DNA)
B. Because it is a major component of bones and teeth
C. As the main energy source for movement and cell processes
D. By providing bacteria in their stomachs for ammonification

Answer 1

A. To build structure made of protein and make genetic molecules (DNA)

This is the best response because nitrogen is essential for building proteins, which are crucial for the growth and development of animals. It is also necessary for the synthesis of genetic molecules like DNA, which are essential for the functioning of all organisms. Without nitrogen, animals would not be able to properly grow, develop, or reproduce, leading to a disruption in healthy food webs.
