Studied by 2 peoplepopulation density
number of individuals per unit area
population distribution
describes the way individuals are spaced out across their range
age structure
the number of males and females of each age in a population
immigration
movement of individuals into an area occupied by an existing population
emigration
movement of individuals out of an area
exponential growth
growth pattern in which individuals in a population reproduce at a constant rate
logistic growth
growth pattern in which a population’s growth slows and then stops following a period of exponential growth
carrying capacity
number of individuals of a particular species that a particular environment can support
limiting factor
factor that causes population growth to decrease
density-dependent limiting factor
limiting factor that depends on population density
density independent limiting factor
limiting factor that affects all populations in similar ways, regardless of the population density
