This organism would live in the aphotic zone, has large eyes to see better with and is able to survive with limited availability of nutrients

• A. Shark
• B. Angler Fish
• C. Starfish
• D. Estuary

Answer: (B)

In the deepest, dark part of the ocean where sunlight doesn’t reach, animals face two big challenges: finding food with very little energy input and detecting anything in near total darkness. Large eyes are a common adaptation in this zone because they help maximize any available light to spot prey or predators. Angler fish exemplify this environment well: they inhabit the aphotic zone, have eyes suited to low light, and rely on a bioluminescent lure to attract prey in an area where meals are infrequent. This combination of enhanced vision in the dark and a feeding strategy designed for nutrient-poor conditions makes them a strong match for living in that zone. Sharks, starfish, and estuaries don’t fit as well because they don’t inherently capture both the deep-dark visual adaptation and the characteristic nutrient-scarce feeding strategy described.
