Answer 1

Metabolic processes produce waste, and a great deal of this is in the form of nitrogen. Nitrogen combines with other molecules in the body to produce toxic compounds such as ammonia and so the animal must find a way to excrete these toxins. As we already know, this is the function of the kidneys and the rest of the renal system.
