Amphibians moved to a terrestrial environment; however, they did not evolve the ability to live their entire lives on land. Expl
Gekata [30.6K]

Answer:

See the answer below

Explanation:

<em>Amphibians are not totally adapted to live on land because the aquatic environment is needed for several life processes such as </em><em>reproduction</em><em>, </em><em>respiration</em><em>, and sometimes, </em><em>feeding</em><em>.</em>

<u>The eggs of amphibians are without any protective shells and will suffer desiccation in the terrestrial environment. Hence, water is needed in order to protect the eggs. In addition, the male am</u>phibians shed their sperm in the water close to the female eggs.

<u>The young ones of amphibians are essentially aquatic and may not survive out of water for a long time because they only breathe gills</u> - the lung is yet to develop or poorly developed at this stage. They have to grow and develop to a certain stage in water before they can start surviving on land.
