Between 45 – 54 years old

Between 55 – 60 years old

5 years

10 years

15 years

1

Species that fulfill a narrow niche and depend on specific requirements for survival are considered

1

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

1

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

1

150 million

200 million

300 million

400 million

0.6%

1.6%

3%

16%
