Biology - Excretory Products and their Elimination Question with Solution | TestHub

Ammonotelic organisms excrete nitrogenous waste primarily in the form of ammonia. Since ammonia is highly toxic and highly soluble in water, it requires a large amount of water for its elimination. Therefore, this mode of excretion is predominantly found in aquatic animals.

Aquatic invertebrates and bony fishes live in water and excrete ammonia, making them ammonotelic.

Birds, land snails, and spiders are terrestrial and need to conserve water, so they are uricotelic (excreting uric acid).

Answer: Aquatic invertebrates and bony fishes
