(Teachers, please copy & format the worksheet below to include space for answers). Unit Objectives # 3,5,11, 14, 15.
Population Vocabulary
Name ______________
Population:
all the individuals of a species that live together in an area
Demography
: the statistical study of populations to make predictions about how a population will change
Three Key Features of Populations -- Size -- Density - Dispersion (clumped, even, random)
Growth Rate
= Birth Rate - Death Rate
-
1. In Voorheesville, 15 babies were born in 2000, 4 residents died. What is the growth rate for Voorheesville? Population =15,243.
-
2. In Acheron, 70 babies were born in 2000, 80 residents died. What is the growth rate for Acheron? Population = 17,256.
Growth Curves
J - Shaped (exponential growth) S - Shaped (logistic model)
Populations are limited by space, food. That limit is called the carrying capacity.
3. At what level do the deer reach their carrying capacity?
What Limits Population Size?
Define Density:
Density-dependent factors: limited resources- space, food, water, air
Density-independent factors: random occurrences that can limit population - earthquake, bad weather
Natural Growth or Mortality Rate = Birth rate -- death rate
Choice factors: Emigration (population moves out) or Immigration (population in)

4. Is disease density dependent, or density independent?
