Which consequence results when elevated CO₂ causes decreased stomatal conductance in C4 grasses?

💡 Explanation

Reduced stomatal conductance decreases transpiration; because of CO₂ concentrating mechanisms, C4 plants face elevated leaf temperatures. These leaf temperatures lead, therefore, to diminished photosynthesis, rather than enhanced water use efficiency characteristic of C3.
