In terms of biomass, deep ocean habitats are similar to Benthic and Abyssal Zones.
the deep or the benthic zone
In terms of biomass, deep ocean habitats are similar to Benthic and Abyssal Zones.
The area underneath the pelagic zone is called the benthic zone, or deep-sea, and is host to silt, sand, and slowly decomposing organisms.
No. Benthic creatures live on the bottom of the ocean. Whales, which have to breath air, may dive deep to feed near the ocean bottom, but they don't live there.
Benthos
how deep the lake is.
They provide nutrients
It's called the Benthic Zone, though this name can apply to deep lakes as well as oceans.
Deep-sea organisms have been difficult to study because the ocean floor is hard to get to.
The deep ocean is often called the Abyssal Zone
Shallow there is more nutrient runoff from onshore
