During an investigation, the rate of photosynthesis in a plant is measured at several temperatures. The investigation is done at three different light intensities. The results are shown. What is the limiting factor for the rate of photosynthesis at point X?
- Alight intensity: no; temperature: no
- Blight intensity: no; temperature: yes
- Clight intensity: yes; temperature: no
- Dlight intensity: yes; temperature: yes
