Answer :
Final answer:
The sunlit zone of the ocean is also referred to as the photic zone, where sunlight supports photosynthesis and a diverse range of marine life thrives. This zone extends down to about 200 meters. Other zones include the benthic, twilight, and abyssal zones, each with distinct characteristics.
Explanation:
Understanding Ocean Zones
One of the critical concepts in marine biology is the division of the ocean into different zones, each characterized by varying light levels, temperature, and habitats. The sunlit zone of the ocean, also known as the photic zone, is the layer where sunlight penetrates enough to support photosynthesis.
This zone extends from the surface down to about 200 meters (656 feet), depending on water clarity. Within the photic zone, a wide variety of marine life can thrive, including phytoplankton, which forms the base of the ocean food web, as well as numerous species of fish and marine mammals.
- **Benthic zone**: The lowest layer of the ocean, which is dark and often home to deep-sea creatures.
- **Twilight zone**: Also known as the mesopelagic zone, where light diminishes but isn't completely absent.
- **Abyssal zone**: The deep sea layer that is in complete darkness and has very high pressure.
In conclusion, the correct answer to your question is that another name for the sunlit zone of the ocean is the photic zone.
