Soon, it was moving around inside with other CO2 and water molecules. Soon, the plant--powered by the sun--began re-assembling the molecule into new forms, adding and subtracting bits with other molecules, to make sweet glucose and release oxygen into the air. A curious rabbit couldn't resist a few nibbles of the sweet leaves with their glucose, and soon the CO2 molecule, in its new form as glucose, was inside the bunny's belly, being converted into energy.</span>
