“Food” generally takes the form of complex organic molecules, largely composed of carbon, oxygen, and hydrogen. Molecules like sugars. When you break these molecules down bond by bond, they release energy–so naturally, the reverse of this process is to *build* these complex molecules by *storing* energy in newly-formed bonds between simpler atoms or molecules.

Plants are able to use the energy of the sun to gradually build up complex organic molecules using water (oxygen and hydrogen) and carbon dioxide (carbon and oxygen). The actual specifics of how this is done is quite complex, but the simple idea is that, and the end product is energy storing molecules and left-over oxygen.
