The Twilight Zone is which pelagic zone?

Explanation:
Light availability with depth defines where each pelagic zone sits. The Twilight Zone is the dimly lit midwater layer where sunlight falls off and is no longer enough to support photosynthesis. That faint light characterizes the mesopelagic zone, which sits roughly from about 200 to 1,000 meters below the surface. In this zone you’ll find organisms adapted to low light—many rely on bioluminescence or vertical migrations rather than relying on photosynthesis for energy. The epipelagic zone above is the sunlit layer where photosynthesis occurs, the bathypelagic zone below is much darker, and the benthic zone refers to the ocean floor.
