You clearly do not know what biological change is vs physical change. You mistake biochemical reactions or chemical reactions with biological change. One is in the realm of atoms and molecules, the other the realm of organisms and species. Biological change entails changes which will effect an organism's reproduction. Chemistry, biology, biochemistry, molecular biology are all different words or terms for a reason. They all mean specific things and relate to specific fields of inquiry.
And you have yet to tell us how "biologicial diversity of the fruit increases dramatically" when it rots. TIt is understandable why you have not elaborated on it because it is nonsense - pretty much equal to gibberish.
You might want to check what this thread is about. I've about seen enough of this act.
