Quizplus · Accepted Answer

Phytoplankton and zooplankton are most abundant in the limnetic zone, which is the open water zone of a lake or pond where sunlight can penetrate and photosynthesis can occur, supporting the growth of these organisms. The benthic zone is the bottom of the lake or pond and may have some plant and animal life, but not as much as the limnetic zone. The littoral zone is the shallow water near the shore, where aquatic plants may grow and animals may feed, but again, not as much as the limnetic zone. The profundal zone is the deep water beneath the limnetic zone where sunlight cannot penetrate and there is very little plant or animal life.
