Question

As the temperature increases above the optimum carban dioxide uptake is.... Due to ....in stomatal resistance
1) increase, decrease
2) increase, increase
3) decrease, increase
4) decrease, decrease

Answer 1

The photorespiration pathway is known to increase with temperature, which means that temperature and CO2 effects predictably oppose one another. This implies that the CO2

-driven metabolic shift will be counteracted by future temperature increases

So opt. 3 is correct
