Question

Numerous small-scale greenhouse and open-top chamber experiments have shown that increases in carbon dioxide concentrations substantially enhance photosynthesis in certain plants. However, the applicability of theselaboratory experiments has been questioned. Why? In these experiments, variables such as temperature and light cannot be controlled properly. These experiments do not have baseline data to validate their results. The results of these experiments usually come from model systems that are too simplified to apply to natural systems.
