b) light is used to synthesize sugars from water and carbon dioxide.

c) light and chemical energy are used to breakdown sugars and other molecules in the presence of carbon dioxide.

d) sugars and other molecules are broken down in the presence of oxygen to produce the energy storage compound atp.
