If you were a plankton in which part of the river would you most likely live a) profundal b) benthic c) limnetic d) sediment?

As a plankton, I would most likely live in the c) limnetic zone of the river. This area is well-lit and supports a diverse range of phytoplankton and zooplankton, allowing for photosynthesis and a rich food web. The profundal zone is too deep and dark for plankton, while the benthic and sediment zones are more associated with bottom-dwelling organisms rather than free-floating plankton.
