← Nature & AnimalsWhich outcome maintains healthy plant-pollinator populations, when soil nitrate levels are critically low?
A)Enhanced microbiome nitrogen fixation rates✓
B)Increased pollination nectar sugar concentration
C)Reduced flower pigment compound expression
D)Decreased root symbiotic bacteria interactions
💡 Explanation
Enhanced nitrogen fixation allows the plant access to more nutrients, enabling it to support pollinators; this is because rhizobia convert atmospheric nitrogen into usable forms via nitrogen fixation; therefore high carbon flow continues, rather than nutrient limitation disrupting both plant and pollinator health.
