The carbon stored in living organisms can move into rocks through several pathways. However, among the options you provided, the most accurate explanation involves the process of living organisms decaying and becoming fossil fuels.
Here's a breakdown of the most relevant pathways:
1. **Decay and Fossilization**: When living organisms die, their bodies can undergo decomposition. Under certain conditions, this organic matter can accumulate and transform into fossil fuels (coal, oil, and natural gas) over millions of years due to heat and pressure. These fossil fuels can later contribute carbon to sedimentary rocks when they get buried and cemented over geological time.
2. **Carbonate Rocks**: Carbon dioxide (CO₂) also dissolves in ocean water, forming carbonic acid, which can react with minerals like calcium carbonate (found in limestone). Over time, the dissolved carbon can help form sedimentary rocks.
3. **Soil Compaction into Rocks**: While organic matter does release carbon into the soil, and soil can become compacted to form sedimentary rocks over geological time, this process typically involves mineral accumulation rather than direct transfer of carbon from organisms to rock.
4. **Respiration and Carbon Dissolution**: The carbon dioxide released through respiration can dissolve in water and may interact with certain rocks, especially limestone, but this is relatively limited compared to the geological processes that form sedimentary rocks.
In summary, the decay of organisms and their eventual transformation into fossil fuels is a significant pathway for carbon to be stored in rocks. Additionally, carbon cycling through ocean chemistry and sedimentary processes plays a role as well.
