← Nature & AnimalsWhich outcome results when soil lacks symbiotic bacteria near soybean plants?
A)Reduced nitrogen availability for plant growth✓
B)Increased phosphorus absorption into the roots
C)Enhanced potassium uptake within xylem
D)Decreased transpiration by the leaf stomata
💡 Explanation
Reduced populations of bacteria inhibit nitrogen availability because nitrogen fixation by Rhizobia converts atmospheric nitrogen into ammonia. Therefore, plants obtain less nitrogen rather than increased phosphorus uptake, because phosphate solubilization mechanisms are distinct.
