Hydrothermal Vents Research Paper

Decent Essays
Hydrothermal vents are the result of seawater percolating down through fissures in the ocean crust in the vicinity of spreading centers or subduction zones places on Earth where two tectonic plates move away or towards one another in the divergent boundary. Hydrothermal vents are like geysers, or hot springs, on the ocean floor.

The discovery happened in 1977, scientists exploring the Galápagos Rift along the mid-ocean ridge in the eastern Pacific noticed a series of temperature spikes in their data. They also realized that an entirely unique ecosystem, including hundreds of new species, existed around the vents. diving in the submersible Alvin 200 nautical miles

Instead of relying on photosynthesis to convert carbon dioxide into organic carbon, the bacteria use chemicals such as hydrogen sulfide to provide the energy source that drives their metabolic processes and ultimately support a wide range of other organisms such as tube worms, shrimp, and mussels.

Chemosynthesis is the synthesis of organic compounds by bacteria or other living organisms using energy derived from reactions involving inorganic chemicals, typically in the absence of sunlight. Chemosynthesis is involved with hydrothermal vents because since the vents are producing a multitude of different chemicals at the bottom of the sea floor the living organisms use that to create energy without the need of sunlight

Examples of organisms found at hydrothermal vents are pompeii worms, tube-dwelling anemones, vent muscle, vent shrimp.

Chemoautotrophs are an organism that obtains energy through a chemical process which is by the oxidation of electron donating molecules from the environment, rather than by photosynthesis.
Examples: Iron bacteria, Sulphur bacteria
Found in: Lava, soil, tissue of deceased animals

Extremophiles are organisms that have been discovered on earth that survive in environments that were thought to not be able to sustain life
Ex Snottites which are actually colonies of cave-dwelling extremophile bacteria that lives off volcanic sulfur, which, when combined with water, produces sulfuric acid.
Tardigrades They can withstand radiation well above what humans can handle
Thermophiles, an organism, type of extremophiles that thrives at relatively high temp.(thrive in temp 140 degrees f to 246 degrees f)

Symbiosis is the interaction between two different organisms living in close physical association typically to the advantage of
