The equation below shows a process that occurs in all green plants. carbon dioxide + water + energy → glucose + oxygen

Which statement about this process is true and supported by the equation?

A: The process follows only the law of conservation of mass and not the law of conservation of energy because the number of atoms stays the same, but energy is used up.

B: The process follows only the law of conservation of energy and not the law of conservation of mass because energy is the same in the products, but the number of atoms increases.

C: The process does not follow either the law of conservation of mass or the law of conservation of energy because the number of atoms increases and the amount of energy is reduced.

D: The process follows both the laws of conservation of mass and of energy because the number of atoms stays the same, and the energy is used to make the products, is stored in the products, and is converted to heat.
