Which 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.
