The rotting of wood is a chemical change because of many reasons. One of the reasons is because when wood rots, it produces mold, which is a new substance. The definition of chemical change is a change that produces one or more new substances. When the wood rots, you are unable to take the rotted wood and mold and make it back into wood that is yet to be rotted. So because the wood produces one (or more) new substances, the rotting of wood is a chemical change.
Yes, food rots under action of some enzymes which chemically breakdown food molecules.
When an apple rots, it's more of a chemical change. Sure, you can SEE the change in it..but the look, is not the actual change. It is a chemical change, catalysed by an organism. The apple wouldn't rot, if there were no chemical change.
