Why do plants produce more carbon dioxide than oxygen during the night?
o
a. respiration can happen without sunlight, but photosynthesis
cannot.
b. respiration can only occur when there is no available sunlight.
o
o
c. photosynthesis only produces carbon dioxide during the night.
o
d. respiration produces oxygen during the day and carbon dioxide at
night.

During daylight hours, plants take in carbon dioxide and release oxygen through photosynthesis, and at night only about half that carbon is then released through respiration. However, plants still remain a net carbon sink, meaning they absorb more than they emit.

The answer is A. Respiration can happen without sunlight, but photosynthesis cannot.
