1 Saccharomyces cereviceae Common name: yeast Eukaryotic Unicellular Cell wall made of chitin Heterotrophic decomposer Asexual reproduction by budding Facultative anaerobe 6,275 genes In nature, found on plants, fruits, and grains Used to make bread, beer, and wine Contributor: Gordon Beakes © University of Newcastle upon Tyne image courtesy Centre for Bioscience, the Higher Education Academy, ImageBank

2 Thermotoga maritima Prokaryotic Unicellular Heterotrophic scavenger Thermophilic Gram-negative Anaerobic using sulfur instead of oxygen Found in deep sea vents and non-marine hot springs 1,879 genes Thermotoga.GIF

3 Escherichia coli Prokaryotic Unicellular Rod-shaped Heterotrophic Gram-negative Facultative anaerobic Found in the intestinal tract Asexual reproduction by binary fission 4377 genes

4 Methanococcus Prokaryotic Unicellular Autotrophic Mesophilic Cocci-shaped Gram-negative Anaerobic Produces methane Found in the deep sea vents, marshes, and intestinal tract ethanococcus_6.gif/300px-Methanococcus_6.gif

5 Sulfolobus sulfataricus Prokaryotic Unicellular Thermophilic Chemotrophic or heterotrophic using sulfur Found in volcanic areas with low
