Question

Human is uriotelic in nature justify

Answer 1

Answer:

I don't have any publication at hand, but I think it's a problem of balance between energy use and saving water. Ammonia is toxic, as mentioned by Anil, 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.

Answer 2

Humans is uriotelic in nature because they are land animals and lives in water scarcity .

• The ammonia in humans is converted into urea in Liver and Kidney.
• Less water is needed for excretion of urea.
• The excretion of urea is known as ureotelism.
• Urea is less toxic in nature.
