Geothermal heat often finds it way to the surface of the Earth, and most often beneath the ocean as there isn't a lot of continental land mass in its way out. When this heat reaches the ocean floor its produces a flurry of chemical reactions with the mud there. This mud is the collected debris of dead algae and other oceanic life that has rained down from above. Now the temperature of the water at ocean floor is 3'C, water colder than that becomes less dense and floats upwards. So the presence of geothermal heat is a Great increase in available energy. All this considered together gives a good habitat for life. The collected nutrients laying dormant there are suddenly made available. Bacteria and other microorganisms capable of using heat for synthetic activities (kinosynthetic) provide a food source for any other lifeforms that is down there: crustaceans tube worms, fish, etc etc etc.

What is the temperatures at deep sea vents?
Some deep sea vents can be hotter than 300 degrees C.
How are deep-sea vents formed?
Volcanic eruptions
Are mollusks found in all habitats?
It would seem so... mollusks have been found near deep sea vents as well as in high altitude mountain ponds (up to 10,000 feet above sea level).
What is the temperature at a deep sea vent?
Some deep sea vents can be hotter than 300 degrees C.
What do geysers and deep-sea vents that from chimneys have in common?
ajhfahfuhgsdiuhguhds
Water released from deep-sea vents has been heated by?
hot rocks deep in the crust.
Chemosynthetic communities in the ocean can be found?
surrounding deep-sea hydrothermal vents
Why are hydrothermal vents helpful to the deep sea ecology?
Hydrothermal vents allow underground heat sources to warm the ocean bottom which is necessary to support deep see ecology.
Propose a question that a scientist might ask about the variety of organisms found around deep sea vents?
How do the unique environmental conditions of deep sea vents influence the biodiversity and genetic adaptations of organisms living in this extreme habitat?
What sea creature has no lungs no brain and no mouth?
Tube worms which live near deep sea hydrothermal vents
The study of the structures of deep-sea vents and of the life around them represents an intersection of which two fields of science?
The study of deep-sea vents represents an intersection of geology (for studying the structures of the vents) and biology (for studying the life around them). Geologists study the geological processes that form the vents, while biologists study the unique life forms that thrive in these extreme environments.
What is the primary source of energy for organisms that live near deep-sea vents?
hydrogen sulfide
