Heterotrophs - An organism is referred to as a heterotroph if it is unable to produce food on its own and must obtain it from other sources of organic carbon, primarily plant or animal matter.
They are heterotrophic communities whose secondary production is dominated by the detrital food chain.
Marine snow, whale falls, chemosynthesis at hydrothermal vents and cold seeps, and dissolved organic matter are the three main sources of energy and nutrients for deep-sea communities.
Many of the organisms that reside at deep-sea vents rely on the chemicals that come out of the vents rather than the Sun, and this process is known as chemosynthesis rather than photosynthesis.
