← Nature & AnimalsWhich process causes nitrogen availability to enhance mutualistic success?
A)Nitrogen fixation creates usable ammonium✓
B)Active transport boosts mycorrhizal spread
C)Endocytosis delivers nutrients intracellularly
D)Chemotaxis guides bacteria towards root exudates
💡 Explanation
Nitrogen fixation by bacteria near plant roots provides ammonium, crucial for amino acid synthesis. This symbiotic relationship benefits both, because this mechanism helps plants access nitrogen, therefore boosting their growth, rather than limiting it to the soil's fixed supply.
