Use the chemical equation for photosynthesis choose the correct number of atoms from the drop down box for the elements shown in the reactions and produces

The chemical equation for photosynthesis is:

6 CO2 + 6 H2O → C6H12O6 + 6 O2

- Carbon (C): 6
- Oxygen (O): 18 (6 from CO2 and 12 from H2O)
- Hydrogen (H): 12
