Question

what is ammonotelic
​

Answer 1

Answer

Most fish are ammonotelic, that is, they excrete waste nitrogen as molecular ammonia or ammonium ion (NH4+). This is the least energetically costly method of nitrogen excretion and in circumneutral waters of low [NH3] is thought to occur largely by passive diffusion of NH3 to the water aided by diffusional trapping of NH3 as NH4+ through acidification of the surface boundary layer (Moreira-Silva et al. 2010)

Explanation:

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.

Answer 2

Excreting soluble ammonia as a result of deamanation is known as ammonotelic
