Which graph best illustrates a population at its biotic potential?
Which graph best illustrates a population that has reached its carrying capacity?
The total fertility rate (TFR) is an estimate of

In the graph below charting the growth of a population of organisms, the line K represents the
Intrinsic rate of the population
Reproductive lag time of the organism
Biotic potential of the organism
Carrying capacity of the population
The world population growth rate in 2015 is about 1 percent. It is expected to drop to 0.5 by 2050, partly because of increased access to birth control in developing nations. Another likely cause for the expected decline is
An increase in the total fertility rate in developed nations
Increasing numbers of women entering the workforce in developing nations
Medical advances that will increase the life spans of people in developing nations
A decrease in the spread of pandemic diseases like Ebola
