    Animal requiring minimum amount of water to produce urine are

    A)  ureotelic          

    B)  ammonotelic

    C)  uricotelic        

    D)  chemotelic.

    Correct Answer: C

    Solution :

    : Fully terrestrial animals can tolerate almost total absence of water in their environment. They need to save every drop of water in their body. Such animals therefore excrete their nitrogenous wastes in the form of solid or semi-solid uric acid (uricotelic), e.g., all insects, terrestrial reptiles and birds. Some urea is also produced in these uricotelic forms, but in desert animals when all the water is reabsorbed in the cloaca then this urea which is absorbed along with the water is recycled through the physiological processes which produce uric acid.
