Answer:
True
Step-by-step explanation:
The reservoir of carbon is located in the ground and consists of soil, rocks, fossil fuels, and other geological formations. These components store carbon for extended periods, impacting the carbon cycle and Earth's climate. Organic carbon in soil comes from decomposed plant and animal matter, while fossil fuels are derived from ancient organic remains buried over millions of years. Thus, the carbon reservoir is comprised of these ground-based elements.
