this biological debris falls through the ocean, a source of nutrition for organisms that live at the bottom
marine snow

This layer is also known as the Midnight zone. Creatures here often use bioluminescence.
Bathypelagic
Attraction of water molecules to other polar substances is called?
What is Adhesion
Why is water called the universal solvent?
