  1. HOW POPULATIONS GROW CHAPTER5 SECTION 1 SC B-6: The student will demonstrate understanding of the interrelationships among different organisms & the biotic & abiotic components of their environment

  2. 3 Important Populastion Characteristics Geographic Distribution Density Growth Rate

  3. Geographic Distribution of Opossum

  4. Population Density • # of individuals / unit area • varies depending on species and ecosystem

  5. 3 Factors Affect Population Size # of births # of deaths #s that immigrate & emigrate

  6. Exponential Growth occurs when the individuals in a population reproduce at a constant rate *under ideal conditions with unlimited resources, a population will grow exponentially see J-shaped curve

  7. LOGISTIC GROWTH • growth pattern in which a population’s growth rate slows or stops following a period of exponential growth • carrying capacity: largest # of individuals of a population that a given environment can support

  8. Carrying Capacity Graph
