Solution

  1. Tadpole (larval stage of life cycle of amphibian) is aquatic. They are ammonotelic as they excrete nitrogenous waste in the form of ammonia.
  2. Ammonia is very toxic and requires large amount of water for its elimination.
  3. It is readily soluble in water and diffuses across the body surface and into the surrounding water.
  4. 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.
  Is there an error in this question or solution?
