Question
Answer the following question.
Amphibian tadpole can afford to be ammonotelic. Justify.
Solution
- Tadpole (larval stage of life cycle of amphibian) is aquatic. They are ammonotelic as they excrete nitrogenous waste in the form of ammonia.
- Ammonia is very toxic and requires large amount of water for its elimination.
- It is readily soluble in water and diffuses across the body surface and into the surrounding water.
- Also, the water lost during excretion can be made up through the surrounding water in ammonotelic organisms.
Hence, amphibian tadpole can afford to be ammonotelic.
