What role do coral reefs play in supporting local fisheries?

Coral reefs serve as critical habitats for a diverse range of marine species, which is why this answer is correct. These ecosystems provide shelter, breeding grounds, and feeding opportunities for fish and other marine organisms, supporting their life cycles. The complex structures of coral reefs enhance biodiversity by offering various niches where different species can thrive. This diverse marine life is crucial for local fisheries, as it sustains fish populations and maintains the balance of the ecosystem.

The other options do not accurately portray the multifaceted role that coral reefs play in supporting fisheries. Providing only high-value fish would overlook the wide range of species that rely on reef habitats. The importance of filtering pollutants and preventing overfishing, while related to marine ecosystems, does not encompass the primary function of coral reefs in relation to fisheries. Their primary role is indeed as habitats that sustain a broader biodiversity essential for healthy fish populations and fisheries.
