← Nature & AnimalsWhich outcome is associated with crassulacean acid metabolism pathways?
A)Minimized photorespiration in arid environments✓
B)Increased nitrogen fixation ability
C)Enhanced phosphorus uptake under stress
D)Greater starch production during rainy events
💡 Explanation
CAM enhances survival; because plants use temporal separation. Therefore, CO₂ fixation occurs at night using PEPCase, rather than during the day with RuBisCO; lessening water loss and increasing efficiency in hot settings rather than C3 which would lose more water.
