This organism would live in the photic zone of the open ocean

• A. Estuary
• B. Turbidity
• C. Light
• D. Shark

Answer: (D)

The photic zone is the sunlit portion of the ocean where enough light penetrates for vision and for many ecological processes. An organism like a shark fits this environment because sharks are open-ocean predators that rely on sight and active hunting in well-lit surface waters. Estuaries are nearshore and often brackish, not the open-ocean photic zone; turbidity describes how clear the water is (a condition, not an organism); light is an abiotic factor, not an organism. So, the shark is the organism that would inhabit the photic zone of the open ocean.
