Photosynthesis and Cellular Respiration Quiz

Which substance is NOT cycled by the processes of photosynthesis and cellular respiration?

• carbon

• ATP

• nitrogen

• oxygen

During photosynthesis producers convert carbon dioxide and other materials to

• lipids

• amino acids

• nucleic acids

• sugars

Carbon is transferred from animals to plants by which molecule?
