During the day, plants photosynthesize, a process that requires sunlight. Photosynthesis is the process by which plants convert carbon dioxide (CO2) from the atmosphere into oxygen and glucose. This process reduces the concentration of CO2 in the atmosphere during daylight hours.

At night, however, plants switch to respiration because there is no sunlight available for photosynthesis. Respiration is the process by which plants convert oxygen and glucose back into CO2 and water. This process increases the concentration of CO2 in the atmosphere during the night.

Therefore, the concentration of CO2 in the atmosphere decreases during the day due to photosynthesis and increases at night due to respiration. This creates a day-night cycle in the concentration of atmospheric CO2. The rapid pulsing seen in the video is likely a visual representation of this cycle.

During the day, plants photosynthesize, a process that requires sunlight. Photosynthesis is the process by which plants convert carbon dioxide (CO2) from the atmosphere into oxygen and glucose. This process reduces the concentration of CO2 in the atmosphere during daylight hours.

Therefore, the concentration of CO2 in the atmosphere decreases during the day due to photosynthesis and increases at night due to respiration. This creates a day-night cycle in the concentration of atmospheric CO2. The rapid pulsing seen in the video is likely a visual representation of this cycle.

Plants continually respire but photosynthesis requires sunlight. Explain how this produces a day-night cycle in the concentration of atmospheric CO2, seen in the video as a rapid pulsing.
