Question:
How have the terrestrial organisms adapted themselves for the conservation of water?
Solution:
The terrestrial mammals or even amphibians mainly excrete nitrogenous wastes in form of urea and hence are known as ureotelic organisms while reptiles, etc. excrete
nitrogenous wastes in form of uric acid and hence are called uricotelic organisms. Thus this is how the conversion of ammonia to urea or uric acid has been the
adaptation that the terrestrial organisms have gone through for conservation of water.
