Which statement is a false statement about a hydrothermal vent? A.
Cold water flows from hydrothermal vents and is warmed by the surrounding water.

B.
Eight-foot long worms and blind fish may live near a hydrothermal vent.

C.
Hydrothermal vents can eventually close up.

D.
Minerals and gases may cause black smoke to flow from a hydrothermal vent.

"Extremophiles" are organisms with the ability to thrive in extreme environments such as hydrothermal vents. Since they live in “extreme environments” (under high pressure and temperature), they can tell us under which range of conditions life is possible.

Through advances in engineering and technology, scientists have been able to explore new habitats and

discover new life forms and metabolic strategies.  Most ecosystems on Earth are sustained by photosynthesis at the base of the food chain. Hydrothermal vent

ecosystems are powered by a process called chemosynthesis that produces energy from chemical reactions.

Like photosynthesis, chemosynthesis results in the production of sugar and other organic compounds through

the fixation of CO2, but it uses chemicals like H2S as the energy source rather than sunlight.

Symbiosis is a close, long-term interaction between two or more different species of organisms. In some

cases, both species benefit from the symbiotic relationship.
