← Nature & AnimalsWhich outcome enhances plant growth in nitrogen-poor soil mediated by fungi?
A)Increased nitrogen fixation✓
B)Decreased phosphate absorption
C)Reduced mycorrhizal network area
D)Enhanced aluminium uptake toxicity
💡 Explanation
Increased nitrogen fixation boosts plant growth because the enzyme nitrogenase converts atmospheric nitrogen to ammonia; therefore, plants benefit from enhanced ammonium as fertilizer, rather than phosphate limitations under non limiting nitrogen.
