Factors or resources that control a process such as organism growth, or population growth or distribution
Examples include availability of food. predation
pressure, or available habitat.
Human populations often appear exempt from limiting factors as technology
and efficiency solve many food and shelter problems. However as the
last arable land is used and agriculture reaches its limits of efficiency, it is
estimated that the human population will peak at around 9 billion by 2050.
22. Using the formula above, determine the annual rate of population change for Mexico. Birth Rate
4.3% Death Rate 1.0% Net Migration Rate 0.0%
23. Using the formula above, determine the annual rate of population change for the United States.
Birth Rate 1.73% Death Rate 0.93% Net Migration Rate 0.20%
24. A population started with a total number of 100 individuals. Over the following year, population
data were collected. Calculate birth rates, death rates, net migration rate, and rate of population
change for the data below (as percentages).
a. Births = 14
b. Net migration = +2
c. Deaths = 20
d. Rate of population change
e. Is the population increasing or decreasing
