Why is ammonia not used as a nitrogenous waste compound in terrestrial animals? a)Ammonia is highly toxic, and to minimize that toxicity it must be excreted in large volumes of water. b)Urea and uric acid both have more nitrogen atoms than ammonia, making them more efficient at c)Ammonia is used by reptiles and birds, because it is less toxic to developing embryos than urea. d)Ammonia has more free energy than urea, so ammonia waste is converted to urea to capture some of that free energy.
