Final answer:
Carbon can be temporarily stored in the biosphere through photosynthesis in plants, which convert atmospheric carbon dioxide into organic carbon.
Step-by-step explanation:
One way that carbon can be stored for a short time in the natural cycle is through photosynthesis in plants. During photosynthesis, plants convert carbon dioxide from the atmosphere into organic carbon, such as glucose, which is used to build plant biomass. This process temporarily holds carbon within the biosphere until it is returned to the atmosphere through respiration by plants or animals, or until the plant material decays.
