Why do we excrete urea instead of ammonia?
Answers
Hey dude here is ur answer....☺️
Excess nitrogen is excreted from the body. Nitrogenous wastes tend to form toxic ammonia, which raises the pH of body fluids. ... In contrast, mammals (including humans) produce urea from ammonia; however, they also form some uric acid during the breakdown of nucleic acids.✌️✌️✌️
Hope this helps you..♥️

Answer:
Explanation:
Ammonia is toxic,and it requires much water to remove from organism so it's produced primarily by water organisms which are not constraint by lack of water. Urea is less toxic and requires less water to remove from organism (so it's better in terrestrial environment) but it requires more energy to produce. And uric acid is most costly in terms of energy but requires the least amount of water to remove. Therefore animals producing uric acid lose a little water with it.
