  1. Levels of Organization

  2. ATOMS • Smallest part of matter • NON-living

  3. Molecules • 2 or more bonded atoms • Form compounds • NON-living

  4. Macromolecule • Very large molecules • Proteins, fats, carbohydrates, nucleic acids • NON-living

  5. Organelles • “Tiny organs” • Made of macromolecules

  6. Cell • Made of organelles • Basic unit of structure & function • LIVING

  7. Tissue • The same kind cell working together • Living

  8. Organs • Tissues that work together • Living

  9. Systems • Organs that work together • Living

  10. Organism • Entire living things (organisms) • Usually made of systems • May be a single cell • Living

  11. Population • Same type of organism living together

  12. Community • Several populations living together • Population interact

  13. Ecosystem • A biotic (living) community plus the abiotic (nonliving) features

  14. Biome • Similar ecosystems on earth together

  15. Biosphere • Whole living layer around the globe • Includes abiotic features http://people.hofstra.edu/geotrans/eng/ch8en/conc8en/envisys.html
