We sometimes find bacteria near hydrothermal vents along the ocean floor...what do they use as an energy source?

	Photic Zone	Aphotic Zone	Benthic Zone	Abyssal Zone
surface --> 200m deep
Zone that sunlight cannot penetrate
found along the ocean floor
Deepest region of the pelagic zone
water is very cold, except near hydrothermal vents
Organisms that need sunlight cannot live here
sunlight is able to penetrate this zone
tubeworms can be found living here
dolphins & jellyfish live in this zone
Currents can change the temperature of the water in this zone
Organisms that live here depend on food scraps to drift down from zones above
