Nitrogenous waste products are eliminated mainly as

1. urea in tadpole and ammonia in adult frog
2. ammonia in tadpole and urea in adult frog
3. urea in both tadpole and adult frog
4. urea in tadpole and uric acid in adult frog

Correct answer: ammonia in tadpole and urea in adult frog

Solution

Tadpoles are aquatic and mainly excrete ammonia because it diffuses easily into water. Adult frogs are more terrestrial and mainly convert nitrogenous waste to urea, which is less toxic and conserves water better.
