A)Atmospheric nitrogen becomes plant-accessible.✓
B)Transpiration rates significantly decrease.
C)Pest resistance dramatically increases.
D)Photosynthetic output sees maximal efficiency.
💡 Explanation
Mutualistic nitrogen fixation enables legumes to thrive because the bacteria convert N2 into ammonia, therefore amino acid production increases, rather than enhanced water retention or generalized stress protections.
