Hydrothermal Vents By Taylor, Jarrad and David

What are Hydrothermal Vents A hypothermal vent is based on the ocean floor and is known as a hot spring, which are found most commonly around the mid oceanic ridges, which allows heated liquids to departs from the earths crust. Material such as iron sulphur and other elements precipitate from these water to form clouds. Which can also be known as black smoker

The various life forms inhabiting this environment 1 Due to there being no sun, which therefore provides no photosynthesis for life, this makes it very difficult to produce life. But in the darkness of the ocean, a certain bacteria, where the answer is held in is relied heavily on due to it being the top factor which produces life in this extreme environment and provides food. The water that come out of the vents are not very rich but not only with dissolved minerals also in chemosynthesis bacteria. They utilize sulfur compounds, which produces organic materials through the process of chemosynthesis. Autotrophs within the bacteria oxidizes hydrogen sulfide within the vent water to obtain water, which is used to produce organic material. Chemosynthetic are primary producers and forms the base of vent food webs.

The various life forms inhabiting this environment 2 New lava on the ocean floor around the vent becomes covered with a thick mat of bacteria. Soon tiny animals such as amphipods and copepods come to feed on the bacteria. And steadily the animals get larger. These are followed by limpets, shrimp, crabs, tube worms, fish, and octopi. A while later acorn worms, dandelion-like animals, and other species of shrimp and tube worms add to the increasing population. In their most higher phases vents are home to mussels, a range of worms, anemones, and a big population of crabs, as well as many of the earlier colonists. AmphipodsCopepods

The conditions of the environment Tremendous Pressure- 300 atmospheres The temperatures within the vents are very extreme, reaching the highest point of heat, 403 degrees Celsius, 100 degrees where tube worms are found, sea water is an average of 2 degrees at depths where vents form, but can be 20 degrees near some vents. Chemicals- hydrogen sulfide, this fuels the vent food web and most valuable compound in vent emissions, but is toxic to most living things. pH- the vent has a pH of 2.8 which is low, very acidic and harmful to most living things
