    It would have been better if you would provide your explanations, and then we could tell you whether you are on the right track or not. But anyway...

    a. 0200 hrs is 2 am, when the plants are respiring and producing CO2. At 1200 (noon) the plants are actively photosynthesizing and removing CO2 from the surrounding air.

    b. At 0400, the lack of light is limiting photosynthesis, but at 1400, the lack of CO2 might be limiting.
