During photosynthesis, carbon dioxide is converted into organic compounds such as glucose, which are stored in plants. This process moves carbon from the inorganic pool (atmosphere) to the organic pool (plants). During respiration, organisms break down organic compounds to release energy, and carbon dioxide is released back into the atmosphere. This process moves carbon from the organic pool (plants or animals) to the inorganic pool (atmosphere). Therefore, photosynthesis moves carbon from inorganic to organic pools, and respiration moves carbon from organic to inorganic pools, making D the correct answer.
