What are uricotelic , ureotelic and ammonotelic excretion. Examples of each type. Let's see who answers first and correctly
Answers
An ammonotelic organism excretes nitrogenous waste as soluble ammonia. 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. The uricotelic organism excretes uric acid or its salts. In comparison to Ammonia and Urea, Uric acid is the least toxic and the least soluble in water. It can be stored in cells and body tissues without toxic effects and thus needs least water and is highly efficient mode of excretion in comparison to two other methods. Uricotelic organisms include terrestrial arthropods (including insects), lizards, snakes, and birds. The excreta of uricotelic organisms is typically white paste.
Answer:
Hey
Uricotelic means uric acid is ejected during excretion.Eg.Birds and reptiles
Ureotelic means Urea is excre ted.Eg.Humans,mammals
Ammonotelic means ammonia is excreted.Eg.All water organisms.
