Population Dynamics

Just some thoughts and questions maybe someone could answer. Not sure if these have been covered yet.When life sprang up, how did it remain in a constant state of balance between herbivores/carnivores/omnivores?Survival of the fittestCarnivores eat herbivores, given lack of foliage for herbivore survival, both run out of food, herbivors die off, carnivor eats itself out-self distruct?Herbivores would have needed appropriate digestive abilities to digest any available foliage currently available. Same beginning cells would have had to split at sometime to grow into plants as well as animals. both different cell make-up.
If only herbivores existed in the beginning, what would be the benefit or possiblity of becoming carnivorous given plenty of foliage?If only carnivorous, would quickly eat itself out.Had each group had to evolve in order to obtain their respective characteristics to ensure survival, how did they survive to begin with?Edited by godservant, : No reason given.Edited by AdminNosy, : No reason given.

I've taken the liberty of changing to a more useful title of your OP.I'll prompt it now for discussion. You can also use it as a google search and do some reading yourself.And a small warning:
What you know about these topics can be measured with negative numbers only. If you are receptive to learning then people will be polite (or else!!) and helpful to you. If you demonstrate an unwillingness to listen you may have to be suspended.
