Question

Are Birds Ammonotelic?

Answer 1

Birds are a group of warm-blooded vertebrates of the Aves class, characterized by feathers, toothless beaked jaws, hard-shelled egg laying, high metabolic rate, a four-chambered heart, and a strong yet light skeleton.

Complete answer:
Birds live worldwide and range in size from 5.5 cm (2.2 in) hummingbird bee to 2.8 m (9 ft 2 in) ostrich bee. There are about ten thousand living species, more than half of which are transient or "perching" birds. Birds have wings, the development of which varies by species; the only known groups without wings are extinct fowls and elephant birds.

Wings, which evolved from forelimbs, gave birds the ability to fly, although further evolution has led to a loss of flight in some birds, including ratites, penguins, and various endemic island species. In addition, birds' digestive and respiratory systems are uniquely adapted for flight. Some bird species in aquatic environments, particularly seabirds and some waterbirds, have developed for swimming.

The process of excreting nitrogenous waste in the form of ammonia is called ammonia. Phenomena is known as ammonotelism. Birds, amphibians, reptiles, most aquatic animals, including fish, some terrestrial invertebrates, larvae and mammals, including humans, excrete urea acid as waste.

The ammonotelic organism excretes nitrogenous waste as a soluble ammonia. The product or waste formed by ammonia is highly toxic. Highly soluble, therefore, it needs a lot of water for its excretion. Species that excrete uric acid waste are referred to as uricotelic organisms. Uricate excreta is usually white paste and insoluble solids or semi-solids. Needs very little water to flush out the uric acid.

No, the birds are not ammonotelic. They are uricotelic organisms that excrete nitrogenous waste in the form of uric acid.

Note: In higher vertebrates, the mesonephric kidney is prevalent in adulthood and consists of an elaborate nephrotic arrangement with a well-developed renal pelvis and a Henle loop that allows for an efficient concentration of urine.
