Briefly and succinctly describe how climate change might affect plant metabolism and crop yield using the following terms.  Note: On a broad scale climate change includes increasing levels of carbon dioxide in the atmosphere which may cause an increase in global annual air temperature and a decrease in precipitation.  Each one of the following nine climatic factors can lead to multiple changes in plant metabolism.  Use the three questions below combined with the climatic factors to help answer this question.   carbon dioxide                C3 photosynthesis                        C4 photosynthesis photorespiration            stomatal conductance                  crop canopy temperature nutrient uptake               crop yield                                        respiration   Increased temperature equals ? Increased carbon dioxide equals ? Decreased precipitation equals ?
