Answer:
Step-by-step explanation:
Freshwater lack has three main zones: littoral zone, limnetic zone, and benthic zone. Littoral zone is the zone of lake present near shore while the limnetic zone is the zone of water present between benthic and littoral zone.
The limnetic zone gets ample of sunlight required by phytoplankton to carry out photosynthesis. Hence the fishes feeding on phytoplankton must be found in this zone.
The benthic zone does not get sunlight to support photosynthesis and phytoplankton are not found in this zone.
