A carbon atom can take multiple forms as it travels through the carbon cycle, including being part of a carbon dioxide molecule. Which of the following statements is correct about the carbon atoms in carbon dioxide
molecules?
A. Carbon atoms from the carbon dioxide molecules used in photosynthesis are reused as carbon atoms in the sugar that a plant produces
B. Carbon atoms from the carbon dioxide molecules used in photosynthesis can be used a set number of times and are then removed from circulation
C. Carbon atoms from the carbon dioxide molecules used in photosynthesis are changed into oxygen atoms which the plant uses to produce glucose
D. Carbon atoms from the carbon dioxide molecules used in photosynthesis are partially converted into energy, therefore reducing the mass of the carbon atoms
