Why is it dark in deep ocean?

Because the light cannot penetrate the deepest layer of the ocean called the 'twilight zone,' simply because of depth. If water were perfectly clear and lacked many microorganisms and additional chemicals, perhaps the deeper parts of the ocean would not be dark. However, ocean water is rich with life and nutrients, and therefore has plenty of light-absorbing factors, leading to a zone by which all light has faded away.
