686574959	Age Structure Pyramid	graphical representation of a population's ages
686574960	Albedo	the fraction of solar energy that is reflected back into space
686574961	Biotic Potential	the amount that the population would grow if there were unlimited resources in its environment
686574962	Carrying Capacity	the maximum population size that can be supported by available resources in a region
686574963	Demographic Transition Model	a model that's used to predict population trends based on the birth and death rates as well as economic status of a population
686574964	Ecological Footprint	the amount of the earth's surface that's required to supply the needs of and dispose of the waste from a particular population
686574965	Genetic Drift	the random fluctuations in the frequency of the appearance of a gene in a small isolated population, presumably owing to chance, rather than natural selection
686574966	K-Selected	organisms that reproduce later in life, produce fewer offspring, and devote significant time and energy to the nurturing of their offspring
686574967	Logistic Population Growth	when a population is well below the size dictated by the carrying capacity of its region, it will grow exponentially, but as it approaches the carrying capacity, its growth rate will decrease and the size of the population will eventually become stable
686574968	R-Selected	organisms that reproduce early in life and often have a high capacity for reproductive growth
