Difference between Ammonotelism, Ureotelism and Uricotelism

 Ammonia, urea and uric acid are the main nitrogenous waste product in different animals. The major role of excretory system is the elimination of nitrogenous wastes. In animals, nitrogenous excretion is grouped into three categories based on the form in which nitrogenous wastes are removed;

1) Ammonotelism 2)Ureotelism and 3)Uricotelism
Difference between Ammonotelism, Ureotelism and Uricotelism:

Ammonotelism, Ureotelism and Uricotelism

Ammonotelism vs Ureotelism vs Uricotelism

Chief nitrogenous waste is ammonia
Chief nitrogenous waste is urea
Chief nitrogenous waste is uric acid
 Solubility: Easily  dissolves in liver cells by deamination of aminoacids
It is less soluble in water
It is almost insoluble in water.
Ammonia is formed by deamination of amino acids in liver cells
Urea is formed in liver and is produced from an amino acid arginine. Arginase is the enzyme involved. 
Potassium ureate reacts with water and carbon dioxide to form uric acid
Ammonia is very toxic
Urea is less toxic
Uric acid has very low toxicity
