When a fuel burns with excess , complete combustion occurs and the products are and . If oxygen is limited, incomplete combustion produces toxic and black (unburnt carbon particles). In your body, undergoes cellular respiration, a controlled form of combustion, releasing for cells to use. Rusting is a slow oxidation reaction that forms (rust) on iron surfaces. Photosynthesis is the reverse of respiration: plants use light energy to convert carbon dioxide and water back into glucose and oxygen.
