Why can't amphibians survive far from water?

Question

Quizplus · Accepted Answer

Amphibians lay their eggs in water or in moist environments, and these eggs do not have an amniotic sac that protects them from drying out. As a result, they are highly dependent on water to keep their eggs moist, and to provide a suitable environment for the development of their young. Without access to water, amphibian eggs would dry out and die. Additionally, adult amphibians have moist skin that needs to be kept wet in order to carry out respiration through their skin, and to prevent dehydration. This makes it difficult for them to survive in dry environments far from water.
