Whether an Animal Excretes Ammonia,uric Acid,or Urea Has Mostly to Do

Question

Whether an animal excretes ammonia,uric acid,or urea has mostly to do with
A)availability of water in its niche.
B)dietary strategies.
C)metabolic costs.
D)all of the above

Accepted Answer

The excretory strategy of an animal mainly depends on the availability of water in its habitat, dietary strategies, and metabolic costs. For example, animals that live in aquatic environments and have access to enough water excrete ammonia, while terrestrial animals require water conservation and excrete urea or uric acid. Similarly, animals with a high-protein diet have a higher nitrogenous waste load, making urea or uric acid excretion more efficient. Finally, metabolic costs, such as the energy required to synthesize different waste products, also play a role. Therefore, all the given options affect an animal's excretory strategy.
