Document Summary

Study of interrelationship b/w microorganisms and ecology ecosystem: community of organisms and environment guild: group of organisms w/ similar processes. Guild 3 lives by substrates for guild phototrophs produce organic matter (light available) fermentation(anaerobic) and supplies. Organisms classified in terms of their energy and c source. Chemo/photo: energy from chemicals/light auto/hetero: carbon source = co2/organic carbon trophy=to eat. Carbon source: heterotrophic (organic compound) and autotrophic (co2) activities commonly measured when studying microorganisms within an ecosystem: primary production of organic matter (phototrophic, chemolithotrophic activity) Co2 + h2o + energy new biomass decomposition of organic matter (chemoorganotrophic/heterotrophic activity) dead biomass co2 + h2o + energy biogeochemical cycling of elements. C, n, p, s, fe necessities for growth: resources (nutrients), suitable physiochemical conditions. Extermophiles psychrophiles: live in cold, -15-10 degree celsius thermophiles: live in hot temps 10-45 hyperthermophiles: live in temps 60+ halophilic archaeons inhabiting hypersaline(high sodium chloride levels) habitats.
