Humans cycle carbon from the biosphere to the atmosphere primarily by respiration. When humans and other organisms respire, they convert glucose and oxygen into carbon dioxide and water, releasing carbon dioxide into the atmosphere. While the other options involve carbon cycling in different ways, respiration is the direct process that transfers carbon from biological systems to the atmospheric system.
