6. What are the two products of the light reactions?

7. What biproduct of aerobic respiration from chapter 4 is used to make sugars in the Dark (Calvin Benson) cycle? (2 points)

8. Is oxygen produced by the light reactions or the Calvin Benson cycle in photosynthesis?

9. Is an autotroph or a heterotroph able to make their own food using sunlight?
