[(6)CO2 + (6)H20] + sunlight = [C6H12O6 + (6)O2]

If you take a tiny acorn and add enough water and sunlight, you get a mighty Oak tree. I'll admit that is terribly impressive, but you should see what happens in our corral. If you take a few flakes of alfalfa hay, add a little water and a few donkeys, you get a towering mountain of manure; and it doesn't take three hundred years to mature, either.
