I used a biology food pyramid as an analogy. For instance, it is impossible for there to exist as many cows as green plants for most of those cows would have to starve to death. This is an important question or variety of questions in biology and needs an answer. What I propose to do in this new theory, tentatively call it Species Creation theory, is to look for energy numbers that has a equilibrium. Think of it this way.
Earth has so much biomass that it can be roughly calculated in terms of energy.
Energy of converting sunrays into organic energy molecules. The photosynthesis kingdom has the dominant number of energy of the total biomass. This number tends to some equilibrium. Now consider the non-photosynthesis kingdoms in comparison. Both are complementary to each other.
