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

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
