Answer 1

The section of the ocean without sunlight is the aphotic zone, exceeding 200 meters in depth and unsuitable for photosynthesis, requiring organisms to rely on chemosynthesis or drifting food from above.

Step-by-step explanation:

The section of the ocean that receives no sunlight is called the aphotic zone. This zone is water deeper than 200 meters and is characterized by an environment where too little sunlight penetrates for photosynthesis to occur. Organisms living in the aphotic zone either rely on food drifting down from above or utilize chemosynthesis to produce food using chemical energy. Most of the ocean's vast volume falls within the aphotic zone, which is distinct from the sunlit photic zone where photosynthesis is possible.
