A bird excretes nitrogenous waste materials in the form of
A bird excretes nitrogenous waste materials in the form of
The correct option is A uric acid
Depending upon the form in which nitrogenous waste is excreted from the body, the organisms are grouped as under into three categories: ammonotelic, uricotelic and ureotelic
Birds excrete nitrogenous wastes as uric acid in the form of pellet or paste with minimum loss of water and are called uricotelic animals. Uricotelic organisms include terrestrial arthropods (including insects), lizards, snakes, and birds.
An ammonotelic organism excretes nitrogenous waste as soluble ammonia. Ammonia the product or waste formed is highly toxic and soluble therefore needs plenty of water for its excretion. Most of the aquatic animals including protozoans, crustaceans, platyhelminths, cnidarians, poriferans, echinoderms, fishes, larvae/tadpoles of amphibians are ammonotelic.
A ureotelic organism excretes excess nitrogen as urea. Urea is less toxic and needs less water in comparison to Ammonia. Ureotelic organisms include cartilaginous fish, few bony fishes, adult amphibians and mammals including humans.
