Solution

Explanation

Ammonia is the most toxic form of nitrogenous waste, hence it cannot be stored in the body.

It also requires a large amount of water to eliminate it.

Since the aquatic animals have large availability of water it is disposed of as ammonia.

Since terrestrial animals have less availability of water, they have evolved to conserve water.

Ammonia is converted into urea, which is comparatively less toxic and requires less quantities of water to discharge.
