Yes, more than at the surfase.
"Mostly in-deep water mainly far out in the ocean".
In deep ocean waters because, it is very dark deep in the ocean and they need some souce of light.
in the deep oceon floor
It is important for organisms that live in the deep ocean to absorb heat, since it is very cold in that region of the ocean. Without the heat, they would die. Some organisms absorb heat from ocean vents, which provide a large amount of heat.
The aphotic zone is permanently dark. Organisms would need to be able to manufacture and obtain food without photosynthesis.
The most common answer would be deep ocean currents.
bacteria and decomposers
They provide nutrients
Deep-sea organisms have been difficult to study because the ocean floor is hard to get to.
Shallow there is more nutrient runoff from onshore
such organisms would be bacteria, fungi, protozoa, algae and other microorganisms mostly you would only need to find a rock and have a powerful microscope
