B) The quantity r is the per capita growth rate and is calculated by multiplying the number of births and the number of deaths.
C) The quantity r is the per capita growth rate and is calculated by subtracting the number of deaths from the number of births.
D) The quantity r is the biotic potential of a population and is calculated by adding the birth rate and the death rate.
E) The quantity r is the monthly net increase of a population and is calculated by subtracting the number of births from the starting population size.
