Name 3 natural carbon sources

Fossil fuels

Respiration

Rocks

Explanation:

Carbon is ubiquitous and found almost everywhere in both living and non-living organisms. It is one of the most essential elements needed for life to function.

The natural sources of carbon include fossil fuels, respiration and rocks

Fossil fuels are energy rich compounds derived from organic matter that has been preserved. The process of respiration releases carbon in form of carbon dioxide into the atmosphere as a by product. Some rocks are predominantly made up of carbon for example diamond and graphite.
