(1) The littoral zone is indeed the shallow, near- shore area where light penetrates to the bottom, allowing rooted plants to grow. (2) The limnetic zone is the open water surface layer away from the shore, where sufficient light is available for photosynthesis, and phytoplankton thrive. (3) The profundal zone is the deep bottom area below the limnetic zone, where light penetration is insufficient for photosynthesis, hence it is a dark zone.
Consider the following statements regarding an aquatic ecosystem: (1) The shallow water zone around the edge of the lake is the littoral zone. (2) Limnetic zone is the open zone where phytoplankton grows in abundance (3) Profundal zone is the dark zone where the light cannot reach. Which of the statements given above is/are correct?
