How does carbon get into the soil and what processes are involved in its transfer?

Carbon enters the soil through the decomposition of organic matter, such as dead plants and animals. This process is carried out by microorganisms like bacteria and fungi. Additionally, plants absorb carbon dioxide from the atmosphere through photosynthesis and store it in their roots and leaves. When plants die, their carbon is also added to the soil. Overall, the main processes involved in the transfer of carbon to the soil are decomposition and plant uptake.
