What happens during the process of decay in the carbon cycle?

• Decomposers break down dead organisms, releasing carbon back into the soil or air.

• Plants take in carbon dioxide to make food.

• Fossil fuels are formed from ancient remains.

• Carbon is trapped in rocks through geological processes.
