Question

Explain Ammonotelism with example.

Answer 1

Ammonotelism is the process of excretion of ammonia and ammonium ions. Such animals are called ammonotelic. Ammonia is highly toxic and must be removed with a great quantity of water. So, ammonotelism can be afforded only by the aquatic animals. Fishes, protozoans, cnidarians, poriferans etc. are ammonotelic organisms.
