Solution - Terrestrial Animals Are Generally Either Ureotelic Or Uricotelic, Not Ammonotelic, Why - CBSE (Science) Class 11 - Biology

ConceptModes of Excretion - Uricotelism

Question

Terrestrial animals are generally either ureotelic or uricotelic, not ammonotelic, why?

Solution

Terrestrial animals are either ureotelic or uricotelic, and not ammonotelic. This is because of the following two main reasons:

(a) Ammonia is highly toxic in nature. Therefore, it needs to be converted into a less toxic form such as urea or uric acid.

(b) Terrestrial animals need to conserve water. 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.

Is there an error in this question or solution?
