Since no light reaches the bottom layer of the water column, there will be no photosynthesis taking place. This means there will be no oxygen production, leading to low dissolved oxygen levels. Additionally, since there is no primary productivity, there will be less biomass and thus fewer predators and prey. Aerobic bacteria may still exist but would likely be limited in their activity due to the lack of oxygen.
