Detailed explanation-1: -The limnetic zone is the open and well-lit area of a freestanding body of freshwater, such as a lake or pond. Not included in this area is the littoral zone, which is the shallow, near-shore area of the water body.

Detailed explanation-2: -The limnetic zone is the open water area where light does not penetrate to the bottom. The third component of the lake habitat is benthic zone which is the bottom of the lake. The profundal zone is the deepest zone in the sea. So the correct answer is ‘Limnetic zone’.

Detailed explanation-3: -The Limnetic Zone is generally classified as the open water area of the lake or pond. This is a much larger section of water in oligotrophic ponds and lakes than it is in eutrophic bodies of water.

Detailed explanation-4: -The limnetic zone is the open water area where light does not generally penetrate all the way to the bottom. The bottom sediment, known as the benthic zone, has a surface layer abundant with organisms.

Detailed explanation-5: -Limnology divides lakes into three three distinct zones (limnetic, littoral and the benthic zone; Fig.).
