The benthic ocean, which is the ocean floor, is home to organisms that rely on chemosynthesis rather than photosynthesis to produce energy. Chemosynthetic bacteria get their energy from chemicals released from hydrothermal vents on the ocean floor, so they would be able to survive without the sun's energy. Other ecosystems rely on the sun's energy to produce food through photosynthesis, so they would be affected more quickly.
