Waste Products Of Animals:

The nitrogenous wastes are urea,ammonia and uric acid. These all wastes are not removed by the same animal. These wastes are produced and excreted by different animal which are living in different habitats. The type of nitrogenous waste and their excretion depend upon the habitat of an animal.

1.Ammonia (NH3):
It is the excretory product of aquatic animals,developes by the break down of amino acids,harmful to the living cells,excreted by diffusion and highly soluble in water.
About 500 ml of water is needed to remove one gram of ammonia.
Animals those excrete ammonia are called ammonotelic.


Examples: Eartworm, protozians, sponges and fishes etc.

2.Urea {CO (NH2)2}:

It is the excretory products of mostly land animals,produced by the liver from ammonia,less toxic than ammonia and can be store in the body for short time.
One gram of urea require 50 ml of water for excretion.
Animals those remove urea are called ureotelic.
Examples:Sharks.Mammals,Adults Amphibiansand Turtles.



3.Uric Acid (C5O3N4H4):

Uric Acid is the excretory product of animals which live in the environment with less supply of water.
These animal do not use more water.
It is harmless and less soluble in water.
One ml of water is required to remove 1 gram of uric acid.
It is excreted in the form of paste or crystal with little water.
Animals removing uric acid are called uricotelic.
Example: Many Reptiles.Insects,Birds land snails,
