The response area is not a recognized carbon reservoir. Carbon reservoirs refer to the various natural and artificial storage areas in which carbon is stored. The main carbon reservoirs include fossil fuels (such as coal, oil, and natural gas), the ocean, terrestrial biosphere (including forests and soil), and the atmosphere. Among these, the largest carbon reservoir is the ocean, followed by the terrestrial biosphere and fossil fuels. The smallest carbon reservoir is the atmosphere.
