Explanation:
Detailed explanation-1: -Respiration in plants happens throughout the day and night thereby carbon dioxide is produced. However, during the daytime, the amount of carbon dioxide released is negligible compared to the amount of oxygen produced as a result of photosynthesis. Hence, one should not sleep under a tree at night.
Detailed explanation-2: -During the day, photosynthesis is dominant, so there is a net release of oxygen. At night, photosynthesis stops but respiration continues, so there is a net consumption of oxygen.
