Question 13 of 32 Which best describes how the total mass of the substances that go into photosynthesis compares to the mass of substances that are present afterward? O A. The mass increases because some light energy changes into mass. B. The mass decreases because plants destroy some of the atoms during photosynthesis. O C. The mass increases because the molecules that are produced are larger than those that are used. O D. The mass stays the same because the total number of atoms does not change SUBMIT​
