Question 3

(Multiple Choice)

Refer to the figure.
Refer to the figure.   The figure shows CO2uptake by various leaf layers in a tropical forest.  -If a native forest with 15 leaf layers is replaced with a palm oil plantation that has 3 leaf layers, there will be a(n) _______ of _______ maximum net CO2uptake because of ________. A) decrease; 0.7 g/m<sup>2</sup>/hr; a reduction in net photosynthesis due to fewer leaves B) decrease; 0.5 g/m<sup>2</sup>/hr; a reduction in net photosynthesis due to fewer leaves C) increase; 0.7 g/m<sup>2</sup>/hr; reduced respiration loss due to fewer inefficient leaves D) increase; 1.2 g/m<sup>2</sup>/hr; a greater proportion of high efficiency with top canopy leaves The figure shows CO2 uptake by various leaf layers in a tropical forest.
