Question

Terrestrial animals are generally either ireotelic or uricotelic not anmonotelic. Why ?

Answer 1

Terrestrial animals are generally either ireotelic or uricotelic not anmonotelic as animals need to conserve water. Since, ammonia is toxic in nature and water soluble and can not be totaly eleminated from body. Therefore, it is required to convert into less toxic form like urea or uric acid and excrete from body.

Since ammonia is soluble in water, it cannot be eliminated continuously. Hence, it is converted into urea or uric acid. These forms are less toxic and also insoluble in water. This helps terrestrial animals conserve water.
