Chapter 5:
Define the term population:
List 5 ways that we can describe a population.
1.
2.
3.
4.
5.
Define geographic range.
Why might a geographic range be limited to a particular area?
What may increase a population’s geographic range? What may decrease a population’s
geographic range?
Define growth rate.
Has the population size in humans increased or decreased in the last 200 years? How has the
growth rate changed?
List some factors that may decrease a population’s growth rate.
List some factors that may increase a population’s growth rate.
Density= ________________/__________________
The above shows the 3 ways a population can be distributed. Describe why a population may
scatter themselves in each way. Which style of distribution is the most common in nature- why
do you think that is?
What is an age structure diagram and why is it useful when describing populations?
Define birth and death rate. Remember the word rate= something changing over TIME
Besides birth and death, how may the size of a population change?
Why might a population immigrate to a particular location? Why might they emigrate out of a
location?
Describe the requirements for a population to undergo exponential growth. Is this realistic?
Draw a graph representing logistic growth. Label and describe 3 phases associated with logistic
growth.
Define carrying capacity. List at least 3 limiting factors that may help a population reach limiting
capacity.
What is the difference between density dependent and density independent limiting factors.
Give 3 examples of each.
Define extinction.
Define demography.
The hypothesis known as demographic transitions, that describes the process of going from
high birth and death rates to low birth and death rates, can be divided into 3 stages. Define what
is going on with the birth and death rates at each stage. At what 2 stage(s) are birth and death
rates equal?
Explain why the leftmost age structure diagram shows rapid growth. Explain why the rightmost
age structure diagram shows negative growth.
