Carbon dioxide concentration is lowest in the morning. True or False?

Explanation:
In aquaculture systems, carbon dioxide levels are shaped by the balance between respiration and photosynthesis. During daylight, algae and plants use CO2 for photosynthesis, so CO2 concentration falls as light increases. The lowest CO2 occurs when photosynthesis is most active, typically around midday to early afternoon. At night, respiration continues without photosynthesis, causing CO2 to rise. So the idea that CO2 concentration is lowest in the morning isn’t accurate, because the lowest point usually occurs later in the day when photosynthesis is strongest.
