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

Tadpoles of frogs are aquatic and excrete nitrogenous waste primarily in the form of ammonia, which is highly soluble in water and requires a large amount of water for its elimination. Thus, they are ammonotelic.

Adult frogs are terrestrial and amphibious. They excrete nitrogenous waste primarily in the form of urea to conserve water. Thus, they are ureotelic.

Therefore, the mode of excretion in tadpole of frog is ammonotelic and adult frog is ureotelic.

Answer: ammonotelic, ureotelic
