Question

Accepted Answer

(d) Birds and Lizards both — The nitrogenous waste uric acid is excreted by birds and lizards both. Birds and reptiles, are most terrestrial arthropods, such as insects are called uricothelic organisms because they convert toxic ammonia to uric acid or the closely-related compound guanine (guano), rather than urea. In contrast, mammals (including humans) produce urea from ammonia. However, they also form some uric acid during the breakdown of nucleic acids. In this case, uric acid is excreted in urine instead of in feces, as is done in birds and reptiles.
