Which statement best describes photosynthesis and respiration?

• Autotrophs carry out photosynthesis, while autotrophs and heterotrophs carry out respiration

• Autotrophs and heterotrophs both carry out photosynthesis and then respiration

• In autotrophs, photosynthesis requires oxygen, and respiration requires carbon dioxide

• Only autotrophs carry out photosynthesis, while only heterotrophs carry out respiration

How are the reactions of photosynthesis and cellular respiration interconnected?

• The reactions are opposites of one another, each using the products of the other as reactants.

• Both reactions require ATP as the energy source, but photosynthesis only happens in plants.

• Every organism carries out both processes at the same time but in different parts of the organism.

• Animals rely on photosynthesis in plants, and plants rely on respiration as the source for their ATP.
