Explanation:
Detailed explanation-1: -So, plants take in carbon dioxide from the atmosphere for preparing food. At night, photosynthesis does not occur hence they take in oxygen and give out carbon dioxide. Therefore, it is said that during the daytime, plants take in carbon dioxide and give out oxygen, and during the night it is vice-versa.
Detailed explanation-2: -Plants excrete more carbon dioxide at night compared to during the day because they cannot do photosynthesis at night. Photosynthesis requires sunlight. So, during the day plants take in carbon dioxide and water and use sunlight to do photosynthesis to make oxygen and glucose.
