Nitrogenous waste is excreted in the form of pellet or paste by:
- Ornithorhynchus
- Salamandra
- Hippocampus
- Pavo
The Correct Option is D
Solution and Explanation
In biology, the excretion of nitrogenous wastes varies among different organisms. Birds typically excrete nitrogenous waste in the form of uric acid, which is less toxic and requires less water compared to ammonia or urea. This is observed in many birds, where the waste is expelled as a white paste or pellet.
Given the options, we need to determine which organism excretes nitrogenous waste as a pellet or paste:
- Ornithorhynchus: Commonly known as the platypus, a mammal that excretes urea.
- Salamandra: An amphibian that typically excretes ammonia.
- Hippocampus: Known as seahorses, can excrete nitrogenous waste as ammonia.
- Pavo: Known as the peafowl, a bird that excretes uric acid in the form of a paste or pellet.
Considering the above information, the correct answer is Pavo as it excretes nitrogenous waste in the form of pellet or paste.

Excretory products and their elimination
The physiological process of the elimination of metabolic waste from the body is called excretion. The excretory products comprise amino acids, carbon dioxide, urea, uric acid, water, and ammonia. Some of the Molluscs and Echinoderms excrete waste products from the body in the form of amino acids. Ammonia is the foremost excretory product in animals, it is derived from the proteins exists in the food we eat.
