Question 1

Match between columns
                        Premises: model for population growth when resources are unlimited

this describes a population that grows slowly at first and then increases rapidly until it reaches carrying capacity
death rate drops fast; birth rate declines slowly
pandemics are examples of this
short life span; many offspring; minimal care of young
use of fossil fuels began
elephants, humans, and dogs all fit into this model
long life spans, few offspring, extended care of young
a portion of a population to be studied
where humans first evolved
clams, insects, and many fish species fit into this model
describes where individuals in a population are relative to one another
a harsh winter is an example of this
given unlimited resources, what organisms will achieve
the number of organisms of a particular population in a given area
the number of individuals added during some interval divided by the initial population size
statistics that describe a population
the number of individuals in some specified area or volume of a habitat
factors that affect the growth of a population regardless of the number of individuals in that population
