← Nature & AnimalsWhich consequence results when ocean iron fertilization increases?
A)Nitrogen fixation is drastically reduced✓
B)Harmful algal blooms proliferation increases
C)Deep-sea anoxic zones diminish steadily
D)Marine snow carbon flux decreases rapidly
💡 Explanation
Increased iron boosts phytoplankton growth, exhausting available nitrate supplies; the *nitrogen fixation inhibition* then results because iron dependent nitrogenases become limited, therefore reducing overall nitrogen availability, rather than only triggering algal blooms under higher nutrient levels.
