This overview highlights various common microorganisms, including cyanobacteria, E.coli, and amoeba, which inhabit lakes, ponds, and the human digestive system. Cyanobacteria are crucial producers in aquatic ecosystems, while E.coli and Salmonella represent bacterial strains found in our intestines, with certain strains posing health risks. Other protists like Paramecium and Euglena exhibit distinct movement mechanisms, while algae and slime molds play essential roles in their habitats—either as plant-like organisms or decomposers. Understanding these creatures is vital for microbiology and ecology.
E N D
Cyanobacteria • A producer bacteria • Common to lakes and ponds in SD
E. Coli (Escherichia coli) • Lives in your intestines • Some strains can be born pathogens
Amoeba • single celled Protist • moves using a pseudopod
Paramecium • Single celled Protist • Moves using cillia
Euglena • Single celled protist • Moves using a flagella
Algae • Plantlike protists • Can be red green or brown (usually multicellular)
Slime-Mold • Fungus-like Protist (decomposer) • Uses pseudopod movement
Salmonella • Salmonella is the genus name • common bacteria in food poisoning • found in the human digestive tract
Yeast • Single celled member of the fungus kingdom • Used to make bread rise
