When discussing population size, we are referring to
a.
the total number of individuals in a population.
b.
the size of the geographic region in which a population is found.
c.
the number of individuals in a population divided by the area of the region covered by the population.
d.
the number of individuals in a population multiplied by the area of the region covered by the population.
e.
the specific type of environment in which a population can exist.
