← GeographyEcosystem collapse expands into fjords following rapid sediment buildup driven by glacial melt, what process is directly suppressed?
A)Benthic-pelagic nutrient coupling✓
B)Glacial isostatic rebound
C)Thermohaline circulation reversals
D)Atmospheric methane hydrate release
💡 Explanation
Benthic-pelagic coupling weakens because sediment smothers benthic organisms, breaking the nutrient cycle; this is eutrophication. Because it suppresses oxygen, excess nutrients and organic material are not recycled by decomposers creating dead zones, therefore this reduces biodiversity, rather than direct geological or atmospheric destabilization.
