Objective • SWBAT describe characteristics of organisms in kingdom Archaebacteria.

Kingdom Archaebacteria • Archaebacteria are single-celled. – Unicellular • Archaebacteria are prokaryotes. – Their cell does not have a nucleus. • Some are autotrophs (produce their own energy); some are heterotrophs (get energy from consuming or decomposing other organisms). • Archaebacteria live in extreme places!

Check For Understanding • What is an autotroph? A. A car. B. An organism that gets energy from eating other organisms. C. An organism that gets energy from decomposing other organisms. D. An organism that produces its own energy.
