How is ammonia produced from metabolism excreted from ureotelic animals?
Options
- ADirectly through the skin
- BAs uric acid in the form of pellet or paste
- CThrough the kidneys after conversion into urea in the liver
- DAs solid waste
Correct answer
C. Through the kidneys after conversion into urea in the liver
Step-by-step solution
The process of excreting ammonia is Ammonotelism. Many bony fishes, aquatic amphibians and aquatic insects are ammonotelic in nature. Ammonia, as it is readily soluble, is generally excreted by diffusion across body surfaces or through gill surfaces (in fish) as ammonium ions. Kidneys do not play any significant role in its removal. Terrestrial adaptation necessitated the production of lesser toxic nitrogenous wastes like urea and uric acid for conservation of water. Mammals, many terrestrial amphibians and marine
