photic and aphotic derive their names fron the root word photo means light that is photic and aphotic zone differ each other in amount of light reaching there
photic zone is directly lit up by by solar energy while aphotic zone is perpetually dark inhabiting least amount of floran fauna
Photic = where there's light Aphotic = where there isn't light, deeper waters.

Since the aphotic zone does not receive sunlight it relys on the photic zone for the sunlight which in terms it does penetrate.

Photic Zone: part of the ocean that receives sunlight Aphotic Zone: area in an ocean where sunlight does not reach and photosynthesis does not occur
Chemoautotrophs do not increase productivity in photic zones because they reside deep down on sea floors (abyssal zone) where no light penetrates. They are, however, active in the aphotic zone where no light from the sun is visible. There, these bacteria and protozoans take both organic and inorganic compounds provided by deep sea vents and become the "algae of the photic zone". Chemoautotrophs are the primary producers in the lower aphotic zone just like algae and phytoplankton is in the photic. The vital nutrients they provide depend on the type of chemoautotroph it is.
The organisms in the aphotic zone depend on the organisms in the photic zone above to die, then drift down into the deep to provide food for the organisms down in the deep. I believe that the dependence of the photic organisms upon the aphotic organisms has to do with the necessity of breaking down the biomaterials and recycling the nutrients back into the system.
