Lesson 1
POPULATION DYNAMICS
• population density
• dispersion
• density-independent factor
• density-dependent factor
• population growth rate (PGR)
• emigration
• immigration
• carrying capacity
• There are population characteristics that are common to all
populations of organisms, including plants, animals, and bacteria.
• Populations tend to be distributed randomly, uniformly, or in
clumps.
• Population limiting factors are either density-independent or
density-dependent.
• Populations tend to stabilize near the carrying capacity of their
environment.
Lesson 2
HUMAN POPULATION
• demography
• demographic transition
• zero population growth (ZPG)
• age structure
• Human population growth rates vary in industrially developing
countries and industrialized countries.
• Zero population growth occurs when the birthrate and immigration
rate of a population equals the death rate and the emigration rate.
• The age structure of the human population is a contributing factor
to population growth in some countries.
• Earth has an undefined carrying capacity for the human
population.
