  3. 3. Ecology is study of interactions between <ul><li>non-living components in the environment … </li></ul><ul><ul><li>light </li></ul></ul><ul><ul><li>water </li></ul></ul><ul><ul><li>wind </li></ul></ul><ul><ul><li>nutrients in soil </li></ul></ul><ul><ul><li>heat </li></ul></ul><ul><ul><li>solar radiation </li></ul></ul><ul><ul><li>atmosphere, etc. </li></ul></ul><ul><li>AND… </li></ul>
  4. 4. <ul><li>Living organisms… </li></ul><ul><ul><li>Plants </li></ul></ul><ul><ul><li>Animals </li></ul></ul><ul><ul><li>microorganisms in soil, etc. </li></ul></ul>
  5. 5. To study Ecology involves… <ul><li>For non-living (abiotic) </li></ul><ul><ul><li>Climatology </li></ul></ul><ul><ul><li>Hydrology </li></ul></ul><ul><ul><li>Oceanography </li></ul></ul><ul><ul><li>Physics </li></ul></ul><ul><ul><li>Chemistry </li></ul></ul><ul><ul><li>Geology </li></ul></ul><ul><ul><li>soil analysis, etc. </li></ul></ul><ul><li>For living (biotic) </li></ul><ul><ul><li>animal behavior </li></ul></ul><ul><ul><li>Taxonomy </li></ul></ul><ul><ul><li>Physiology </li></ul></ul><ul><ul><li>mathematics (population studies) </li></ul></ul><ul><ul><li>etc. </li></ul></ul>
  6. 6. Ecology… <ul><li>views each locale as an integrated whole of interdependent parts that function as a unit. </li></ul>tundra caribou
  7. 7. The interdependent parts are…
  8. 8. <ul><li>Nonliving </li></ul><ul><ul><li>dead organic matter </li></ul></ul><ul><ul><li>nutrients in the soil and water. </li></ul></ul><ul><li>Producers </li></ul><ul><ul><li>green plants </li></ul></ul>Tundra

  10. 10. ECOLOGY: Levels of Organization - a hierarchy of organization in the environment
  11. 11. Levels of organization - Terms <ul><li>Biosphere </li></ul><ul><ul><li>Surface of the earth </li></ul></ul><ul><ul><li>Composed of many ecosystems </li></ul></ul><ul><li>Ecosystem </li></ul><ul><ul><li>Large or small as we decide </li></ul></ul><ul><ul><ul><li>Backyard, O’Melveney Park, Hedge along Room 110, etc. </li></ul></ul></ul>
  12. 12. Levels of organization - Terms <ul><li>Population – one species live in one place at one time </li></ul><ul><li>Community – All populations (diff. species) that live in a particular area. </li></ul>
  13. 13. Levels of organization - Terms <ul><li>Habitat – physical location of community </li></ul><ul><li>Organism – simplest level of organization </li></ul>
  14. 14. <ul><li>Very complex </li></ul><ul><li>Can contain 100’s to 1000’s of interacting species. </li></ul>
  15. 15. THEN… Ecology is an integrated and dynamic study of the environment.
