Explanation:

Carbon reservoirs are parts of the Earth that store carbon. The atmosphere contains carbon dioxide. Fossil fuels (like coal, oil, gas) are made of carbon - based compounds. Rocks (such as limestone - \(CaCO_3\)) have carbon. Oceans dissolve carbon dioxide. Living things (plants, animals) have carbon in their bodies (e.g., in organic molecules like carbohydrates, proteins).
