You would fine sediment in the benthic zone, or bottom, of a lake.
dead plants and animals that drift from the surface
The littoral zone of a lake is the near the shore area where sunlight penetrates all the way to the sediment and allows aquatic plants to grow. The benthic zone is the region at the lowest level of a body of a lake including the sediment surface and some sub-surface layers.
In the benthic zone, the water is deeper and often has lower light penetration compared to the littoral zone, where sunlight can easily reach the substrate, supporting plant growth. Additionally, the benthic zone may have different sediment characteristics and reduced nutrient availability, making it less hospitable for many aquatic plants. These factors combined limit the ability of plants to photosynthesize and thrive in the deeper waters of the benthic zone.
no plankton do not eat plants
No, plankton do not eat ocean plants. Plankton eat phytoplankton, and phytoplankton use photosynthesis to retrieve energy from the sun.
There are some types of plankton that can eat plants.
Phytoplankton
There are two sorts of plankton, zoo plankton and phytoplankton. Phytoplankton are plants and are producers while zoo plankton are animals that eat other plankton.

yes
Microscopic plants. Such plants are like plankton.
