Here are the answers to the questions based on the oceanic zones:
-
In which zones is sunlight available for photosynthesis?
- Epipelagic Zone (Zone 4) - This is the only zone where sunlight penetrates enough to support photosynthesis.
-
Which zones are dark, with no sunlight?
- Hadopelagic Zone (Zone 1)
- Abyssopelagic Zone (Zone 2)
- Bathypelagic Zone (Zone 3)
- All of these zones are dark, with no sunlight.
-
In which zone do you find the least amount of life?
- Hadopelagic Zone (Zone 1) - This zone has the least amount of life due to extreme depths and pressures.
In summary:
- Sunlight available for photosynthesis: Epipelagic Zone (4)
- Dark, with no sunlight: Hadopelagic Zone (1), Abyssopelagic Zone (2), Bathypelagic Zone (3)
- Least amount of life: Hadopelagic Zone (1)
