Final answer:

Plants excrete more carbon dioxide at night primarily due to photosynthesis using some of the released carbon dioxide during the day.


Explanation:

Plants excrete more carbon dioxide at night than during the day primarily because:

  1. Photosynthesis uses some of the carbon dioxide released during the day.
  2. The light-independent reaction of photosynthesis that releases carbon dioxide occurs at night.

During respiration, carbon is removed from organic materials and expelled as carbon dioxide, which happens continuously, not just at night.
