  3. 3. What is Ecology?? <ul><li>The study of interactions that take place between organisms and their environment . </li></ul><ul><li>It explains how living organisms affect each other and the world they live in. </li></ul>copyright cmassengale
  4. 4. Habitat & Niche <ul><li>Habitat is the place a plant or animal lives </li></ul><ul><li>Niche is an organism’s total way of life </li></ul>copyright cmassengale
  5. 5. The Nonliving Environment <ul><li>Abiotic factors - the nonliving parts of an organism’s environment. </li></ul><ul><li>Examples include air currents, temperature, moisture, light, and soil. </li></ul><ul><li>Abiotic factors affect an organism’s life. </li></ul>copyright cmassengale
  6. 6. The Living Environment <ul><li>Biotic factors - all the living organisms that inhabit an environment. </li></ul><ul><li>All organisms depend on others directly or indirectly for food, shelter, reproduction, or protection. </li></ul>copyright cmassengale
