Most Amphibians are Completely Dependent on an Aquatic Environment for ____

Question

Most amphibians are completely dependent on an aquatic environment for ____.  
A) respiration
B) feeding
C) reproduction
D) movement
E) thermoregulation

Accepted Answer

Most amphibians lay their eggs in water and their larvae develop into tadpoles, which need water to survive and grow. Therefore, amphibians are completely dependent on an aquatic environment for reproduction. While some amphibians may use their skin for respiration, they can also breathe through their lungs or gills, depending on their life stage, so respiration is not completely dependent on an aquatic environment. Feeding, movement, and thermoregulation may also occur on land or in water, depending on the species.
