POPULATION GROWTH
LINEAR POPULATION GROWTH WHAT DO YOU THINK IT MEANS? ? Talk at your table about your understanding of the words “linear”, “population”, and “growth”. Be ready to share!
LINEAR POPULATION GROWTH WHAT DO YOU THINK IT MEANS? ? Linear Population Growth
LINEAR POPULATION GROWTH DEFINITIONS: Linear – in the form of a line Population – amount of organisms in an area Growth – increasing in numbers
NOTES “Normal” Steady line shape rate of growth that is consistent over the generations
EXPONENTIAL POPULATION GROWTH WHAT DO YOU THINK IT MEANS? ? Talk at your table about your understanding of the words “exponential”, “population”, and “growth”. Be ready to share!
EXPONENTIAL POPULATION GROWTH WHAT DO YOU THINK IT MEANS? ? ? § Exponential Population Growth
EXPONENTIAL POPULATION GROWTH DEFINITIONS: Exponential – keeps doubling; the bigger it gets, the faster it grows. Population Growth – amount of organisms in an area – increasing in number
NOTES “J” curve Slow initial growth and then a rapid population explosion after *This can occur when there are no limits to a population size.
WHEN WOULD THERE BE “NO LIMITS” Any ideas?
SO, WHAT DOES IT LOOK LIKE MATHEMATICALLY? ? ? Linear? Exponential?
LINEAR VS EXPONENTIAL GROWTH
EXAMPLE USING FISH Click the picture to see an example of the exponential growth of a fish population.
STUDENTS - PROVIDE EXAMPLES OF “FACTORS AFFECTING POPULATION GROWTH” What term do we give to the “things” you just listed? ?
SAMPLE LIMITING FACTORS AFFECTING POPULATION GROWTH Humans! Weather! (Why does this make sense? !) Predators! (provide an example!) Habitat! (explain HOW this makes sense!) (Is this true in all cases? Explain…) Food! (convince us that this makes sense!)
RATE YOUR LEARNING! Use the generic scale: 0 = I’m don’t get this at all! 1 = I get some of it 2 = I get most of it 3 = I totally get this! 4 = I can help teach someone else this! Now, talk at your tables about your learning. Can you help someone there? Do you need help from someone there? Be ready to chat with your teacher!
