As the plants use up carbon dioxide during the day and give out oxygen during this process, they also respire during the night, a product of which is carbon dioxide. This is why the levels of carbon dioxide will remain the same and level of oxygen will rise because they are photosynthesizing for a longer period during the day than they are respiring during the night.
