The benthic zone is the ecological region at the lowest level of a water body such as ocean or lake.


It also includes the sediment surface and some sub-surface layers.
The superficial layer of the soil lining the given body of water is an integral part of the benthic zone, as it greatly influences the biological activity that takes place there.

Examples of contact soil layers include sand bottoms, rocky outcrops, corals and bay mud. The organisms generally live in close contact with the substrate bottom and many are permanently attached to the bottom.

As light does not penetrate very deep into the ocean water, the dead and decaying matter that drifts from the higher layers sustains the benthic food chain. Most organisms in this zone are scavengers or detritivores.
