Answer:
D
Step-by-step explanation:
The correct answer is D) 200m
Photosynthesis is a process that occurs in plants and algae, which allows them to use sunlight to produce energy from carbon dioxide and water. In the open ocean, photosynthesis can occur to a certain depth where there is enough sunlight to support the process. This depth is usually around 200m, beyond which there is not enough light for photosynthesis to occur.
Epipelagic zone (ocean surface to 200 meters deep). This is the zone in which photosynthesis can occur, because light is available.
So D
