Which feedback on coastal ecosystems results when large gyres stagnate?

💡 Explanation

Stagnant gyres disrupt nutrient cycling because decreased water mixing reduces nutrient upwelling, resulting in nutrient depletion along coastal margins. Therefore, limited nutrients inhibit phytoplankton growth, rather than enhancing carbon sequestration, which happens with nutrient abundance.
