← Nature & AnimalsWhich consequence results when high soil acidity inhibits free-living diazotroph activity?
A)Available soil nitrogen is reduced✓
B)Mycorrhizal phosphorus uptake decreases
C)Plant disease resistance greatly improves
D)Decomposer fungi population rapidly expands
💡 Explanation
When soil becomes highly acidic, nitrogen fixation by diazotrophs slows down because enzyme activity is pH-sensitive, therefore less inorganic nitrogen is available to plants, rather than enhanced nutrient uptake or disease resistance, which need nitrogen.
