    The diagram below represents events associated with a biochemical process that occurs in some organisms. Which statement concerning this process is correct?
    • A. 

      The process represented is respiration and the primary source of energy for the process is the Sun.

    • B. 

      The process represented is photosynthesis and the primary source of energy for the process is the Sun.
