Final answer:
Soil facilitates the conversion of organic matter to CO₂ through microbial decomposition, playing a key role in the carbon cycle.
Explanation:
Soil plays a crucial role in converting organic matter back to carbon dioxide. When plants die, soil microorganisms decompose the dead plant material, releasing carbon dioxide through respiration. This process is a part of the carbon cycle, where carbon is returned to the atmosphere as CO₂.
