Why are frogs usually found in an environment with a water source?
Because frogs are amphibians, (frogs, toads, salamanders, newts) they are non-amniotic, meaning that they do not have a terrestrially adapted egg. Because amphibian eggs do not have an egg shell to keep the amnion (egg fluid) from drying out, amphibians must lay their eggs in the water. Also, amphibians have very thin epidermal membranes (skin) whereas reptiles usually have waterproof scales or osteoderms (as in crocodilians) Amphibians skin (with the exception of some toads) needs to be kept continuously moist. (some amphibians can even do O2 and CO2 exchange through their skin in water) However, the primary reason amphibians stay close to water is because they cannot lay their eggs out of the water.
Amphibians are most dependent on an aquatic environment for?
Amphibians do not have the waterproof skin that amniotes (reptiles, birds, and mammals) do. If they are not wet, they can dry out and die, especially because many types of amphibians breath partly or entirely through their skin. Amphibians also need an aquatic environment in order to breed, because their eggs and young must be in water, or they will dry up and die.
