Yeah For Bacteria!  Ochobactrum anthropi used to help clean up oil spills  Archaebacteria died millions of years ago producing methane, a part of natural gas  Used in production of buttermilk, yogurt and cheeses  Decomposers- recycling Earth’s matter  Nitrogen fixing bacteria in plants like peanuts and soybeans that help the plant use the nitrogen it needs to grow

Bad Bacteria! Bacteria such as Staphylococci which causes staph infections and Streptococci which causes Strep Throat cause bacterial infections. Lobar pneumonia, meningitis, sepsis are caused by bad bacteria. infections…..infections ….. infections! Most bacterial infections can be treated with antibiotics, however overuse of antibiotics have caused bacteria to become resistant to the drugs. Flesh Eating Bacteria Botulism - Bubonic Plague -

Other Unicellular Organisms Eukaryotes- have a nucleus Paramecium moving with cilia

Euglena moving with a flagellum

Amoeba moving with pseudopods
