Answer: Put (Carbon source)
Since I’m sure it’s a “short term” answer
Explanation: Fossilization can be considered both a carbon sink and a carbon source, depending on the specific context and timeframe being considered.
In the short term, fossilization can be seen as a carbon source. When organic matter such as plants and animals die, their remains undergo decomposition by bacteria and other organisms. During this process, carbon is released into the atmosphere in the form of carbon dioxide (CO2) or methane (CH4), both of which are greenhouse gases that contribute to global warming. This release of carbon occurs relatively quickly in geological terms, within a span of years to centuries.
However, in the long term, fossilization acts as a carbon sink. Fossilization is the process by which organic matter is preserved in sedimentary rock over millions of years. During this process, the organic material undergoes various chemical changes and is gradually transformed into fossil fuels such as coal, oil, and natural gas. These fossil fuels contain large amounts of carbon that were originally extracted from the atmosphere by plants through photosynthesis.
