Question

An aquarium fish and a pigeon were fed on protein diet. In what different forms would they excrete their nitrogenous waste ? name the process.

Answer 1

As fish is a ammonotelic animal it will excrete ammonia as N2 waste and this process is called ammonotelism.
As pegion is a uricotelic animal it will excrete uric acid as waste and the process is urico telism.

Answer 2

Nitrogenous waste

Explanation:

Most fishes are ammonotelic which means they excrete waste nitrogen as molecular ammonia or ammonium ion

In case of aquarium fish, they are fed protein diet and protein contains nitrogen so they utilize nitrogen from protein and metabolize to produce ammonia hence called ammonotelic

Animals which secrete uric acid as nitrogenous waste are called uricotelic, pigeon is such an example

Pigeon utilizes nitrogen and and metabolize to produce uric acid
