Carbon is found in several reservoirs. Here are the correct selections:
- Atmosphere: Carbon is present in the form of carbon dioxide (CO2) and methane (CH4).
- Fossil Fuels: Carbon is stored in fossil fuels such as coal, oil, and natural gas.
- Ocean: The ocean contains dissolved carbon dioxide, as well as carbon in the form of organic matter and carbonate minerals.
- Living Organisms: All living organisms are composed of carbon-based compounds.
- Rocks: Carbon is found in rocks, primarily in the form of carbonates (like limestone) and organic carbon in sedimentary rocks.
So, all the options listed are correct.
