← Nature & AnimalsWhich consequence results when increased soil acidity inhibits Rhizobium-legume interactions?
A)Enhanced phosphate uptake by roots
B)Diminished ammonia production in nodules✓
C)Accelerated leaf senescence signaling
D)Increased plant toxin biosynthesis
💡 Explanation
Reduced soil pH decreases the expression of Rhizobium genes necessary for nitrogen fixation and nodule development, because the inactivation prevents atmospheric nitrogen from being converted to ammonia within nodules. Therefore, ammonia production diminishes within the plant rather than accelerating growth or toxin creation.
