Why is it vital for living things such as frogs to digest food?

Answer 1

It is NOT vital for frogs, (or other animals) to eat living creatures. What is vital is oxygen and water. Without those things, they will die for certain. But, the living creatures that they consume as food, provides them with an almost instant stimulation of false energy. I say false because it over time, destroys their bodies from the inside out,(to consume creatures). The stimulation comes in the form of the toxic byproducts that are produced in the bodies as the digestion takes place, much the same way a drug might work in a human body when taken for the same purpose: it may provide a false, instant energy, but essentially it does NOT vitalize the human body at all; it destroys its vitality. This is why frogs eventually die.
