Question

What mode of excretion is found in fishes and frogs?

Answer 1

Excretion:

1. Excretion is the process of removal of nitrogenous wastes or harmful metabolites from the body.
2. The process of excretion is essential in all organisms as it maintains osmoregulation in the body.
3. Excretion helps in maintaining the pH of the body and prevents the internal organs to be damaged by nitrogenous wastes.

In fishes and frogs:

1. The organisms that release ammonia as a waste product during excretion are called ammonotelic and the process of excretion of ammonia is known as ammonotelism.
2. Ammonotelism is commonly seen in fishes and aquatic amphibians (frogs).
