Presentation Transcript

  1. Population Growth

  2. Imagine you left an apple in your locker for a week • When you put the apple in there, there were no flies • A week later, there are tons of fruit flies • Your locker ecosystem had a huge change • Changes in population size and densities are normal

  3. BOX A • What would happen to the fruit fly population in the locker if the apple were removed? Explain

  4. Population Size (Box B) • Population size change in every population

  5. Growth Patterns • There are 2 types of growth patterns • In Doodle Box C – copying the example graphs

  6. Exponential Growth • No limit to growth • Breeding uncontrolled • No factors that limit its size • More births than deaths • Examples: Bacteria

  7. Logistic Growth • Ecosystem can only support a certain amount (Carrying Capacity) • There is maximum # of individuals it can support
