Heat causes the breakdown of starches (long chain carbohydrates) into simpler to digest sugars (mono and dimer carbohydrates). This involves breaking chemical bonds, so it is a chemical change.

Is heat on cupric carbonate a chemical or physical change?
It depends on how much heat is added; for instance: Chemical change indicates a change in the chemical formula. Heating it would eventually decompose it, so it is a chemical change if you are decomposing it. A change in phase (solid-->gas) would be a physical change, so as long as the chemical formula stays the same, meaning it doesn't react with anything in the air or decompose, it would be a physical change
