Ammonia is a small, water-soluble molecule, and its removal from the body requires a significant amount of water. In organisms that excrete ammonia, such as the tadpole stage of frogs, this process is more common in water-dwelling species. What type of animals primarily excrete ammonia?

1. Land-dwelling animals expel ammonia.
2. Water-dwelling animals expel ammonia.
3. Amphibians expel ammonia.
4. Reptiles expel ammonia.

Correct answer: Water-dwelling animals expel ammonia.

Solution

Ammonia must be diluted heavily to be safely excreted, so animals with constant access to water can eliminate it most easily. That is why water-dwelling animals, including aquatic stages like tadpoles, primarily excrete ammonia.
