Which outcome arises when a gyre's density gradient weakens?

💡 Explanation

Reduced density gradients stall the **downwelling** mechanism, restricting nutrient cycling because denser water no longer sinks to drive vertical mixing; therefore, nutrient supply into the photic zone decreases, rather than enhanced upwelling or altered weather.
