Solution:

Urea, uric acid and ammonia all are nitrogenous wastes. Ammonia is highly toxic and highly soluble in water, therefore, requires a larpg amount of water for excretion. Urea is less toxic and less soluble in water than ammonia. Uric acid crystals are non-toxic and almost insoluble in water.
