A farmer grows a crop in a closed greenhouse. During a sunny summer day, the light intensity, temperature and carbon dioxide concentration inside the greenhouse all change.
Explain how the interaction of light intensity, temperature and carbon dioxide concentration limits the rate of photosynthesis of the crop from dawn until the middle of the afternoon.
