Juvenile amphibians (i.e., amphibians that still live exclusively in water) excrete nitrogenous waste in the form of ammonia instead of urea. Why Ammonia is less toxic than urea Juvenile amphibians want to maximize energy expenditure Ammonia is not soluble in water and can be excreted as a paste Ammonia cannot be lost across the body surface via diffusion Synthesis of ammonia requires less ATP than synthesis of urea
