Explanation:
Limnetic zone is the water area zone where light does not penetrate the bottom as the depth of the water is more towards the center whereas littoral zone is the zone near shore area which is shallow and where plants grow and sunlight penetrates all way in this area. Littoral zone surrounds the limnetic zone in the lake and ponds because the rest of the water bodies mentioned in the question have free flowing water.
