Reactant:
* Combustion: CO2 is a product of burning fuels like wood, propane, or gasoline. In these reactions, oxygen and the fuel are the reactants, and CO2 is produced.
* Photosynthesis: Plants use CO2 as a reactant along with water to produce glucose (sugar) and oxygen.
Product:
* Cellular Respiration: Animals and plants break down glucose in the presence of oxygen to produce energy. CO2 is a byproduct (product) of this process.
* Decomposition: When organic materials decompose, they release CO2 as a product.
In summary: CO2's role as a reactant or product is determined by the specific chemical reaction it is involved in.
