The Classification System
An Interactive PowerPoint Presentation by Stacey Podolsky
The Classification System
Why do scientists classify?– All living organisms
have characteristics which distinguish them from nonliving objects
– Scientists organize liviving things into groups so that s so that organisms are easier organisms are easier to studyto study
There Are Seven Levels of There Are Seven Levels of ClassificationClassification

• Eubacteria and Archaebacteria– A growing number of researchers now divide this
kingdom into 2 separate kingdoms• Eubacteria
– “The true bacteria”– Autotrophic and heterotrophic– Can cause: strep throat, used to produce yogurt,
vitamins, etc.• Archaebacteria
– Autotrophic and heterotrophic– Live in: hot springs, on the ocean floor, salty water,
your intestines
