APES Population || All Questions Answered Correctly.
population ecology correct answers The study of populations in relation to the environment,
including environmental influences on population density and distribution, age structure, and
variations in population size
population density correct answers number of individuals per unit area
birth rate correct answers the number of babies born per 1,000 people in an area
death rate correct answers the number of deaths per 1,000 people in an area
growth rate correct answers the natural increase of a population, expressed as percent per year
dispersal correct answers movement of individuals among populations
immigration correct answers dispersal of individuals into a population from another area or
country
emigration correct answers dispersal of individuals from a population, bound for another are or
country in which to live
natural increase rate correct answers The percentage growth of a population in a year, computed
as the crude birth rate minus the crude death rate.
biotic potential correct answers maximum rate at which a population could increase under ideal
conditions
exponential population growth correct answers Growth of a population in an ideal, unlimited
environment, represented by a J-shaped curve when population size is plotted over time.
environmental resistance correct answers All the limiting factors that tend to reduce population
growth rates and set the maximum allowable population size or carrying capacity of an
ecosystem
carrying capacity correct answers (K) represents the largest population that can be maintained for
an indefinite period by a particular environmnet
survivorship correct answers probability that a given individual in a population will survive to a
particular age
density- dependent factor correct answers an environmental factor whose effects on a population
change as population density change: it tends to retard pop. growth as population density
increases and enhance pop growth as pop density decreases
