How does energy acquisition in the deep sea differ from energy acquisition near the ocean’s surface?

Sunlight penetrates only the upper layers of the ocean, so organisms in the deep sea cannot use it directly for photosynthesis. Near the surface, sunlight supports photosynthesis, while deep-sea organisms may obtain energy from food or from chemical energy through chemosynthesis. Therefore, the correct choice is “Organisms in the deep sea do not have direct access to sunlight.”
