← Nature & AnimalsWhich risk is amplified when some desert plants experience extended drought conditions?
A)Photorespiration impairs photosynthetic efficiency✓
B)Increased nitrogen fixation in root nodules
C)Accelerated decomposition by soil microbes
D)Decreased nutrient uptake by mycorrhizae
💡 Explanation
Photorespiration rises due to stomata closing to conserve water, increasing O₂ concentration and causing Rubisco to fix oxygen rather than CO₂, therefore wasting energy and slowing growth rather than the other choices, because drought only impacts water efficiency.
