Bacterial Mats With Vents

Chemolithoautotrophic bacteria derive nutrients and energy from the geological activity at hydrothermal vents to.

Bacterial mats with vents.

The chemosynthetic bacteria grow into a thick mat covering the hydrothermal vent and this is the first trophic level of the ecosystem. These bacteria form the basis of the entire hydrothermal vent ecosystem. A microbial mat is a multi layered sheet of microorganisms mainly bacteria and archaea and also just bacterial microbial mats grow at interfaces between different types of material mostly on submerged or moist surfaces but a few survive in deserts. Microbial mats have been found associated with environments such as the benthic planktonic interface of hot springs deep sea vents hypersaline lakes and marine estuaries.

The hydrothermal vent microbial community includes all unicellular organisms that live and reproduce in a chemically distinct area around hydrothermal vents these include organisms in the microbial mat free floating cells or bacteria in an endosymbiotic relationship with animals. A and b filamentous sulfur mat formation on the trac at vent site m. Like plants and algae on land and in shallow waters the vent microbes are the primary producers in their food web and are eaten by larger animals.

Vent bacteria can synthesize all the compounds they need to live from these nutrients a process called chemosynthesis. They colonize environments ranging in temperature from 40 c to 120 c.
