A. Population Biology Concepts
1. Use the axes to the right for the following:
1. Draw and label a line that represents linear growth.
2. Draw and label a line that represents exponential growth.
2. List the four most populated countries in the world.

3. On the axes to the right, draw a line showing a population that
exemplifies logistic growth. (s-curve) and label the carrying
capacity.
4. Perfor
m the following calculation. Show all of your work. In a
particular year a population has the following characteristics:
the crude birth rate is 45, the crude death rate is 20, the
immigration rate is 1%, and the emigration rate is 0.5%. The
percent rate of growth for that year is __________.

5. List two characteristics of an r-selected species.
6. List two characteristics of a K-selected species.
7. Draw a survivorship curve for R- vs. K- selected species. Label the environmental resistance and
biotic potential.
1. In what regions of the world is population density the greatest concern? How is population
distribution a food and water security issue?
2. Explain two reasons why a population can continue to grow even if fertility rates decrease.
3. Perform the following calculations: (Show all of your work in a logical progression to the final
answer.)
1. A city has a population of 50,000 in 2012. If the population of the city grows at an annual rate of
2%, the year in which the population will reach 100,000 is _____________ and the year it will
reach 200,000 is _____________.

2. A country’s population was 12 million in 1992 and in 2012 it is 24 million. If the population grew
at a constant rate, that percent rate of growth was _____________.

4. Write an equation for the rule of 70:
5. Use the axes below to draw and label lines representing the birth rate, death rate and total
population size during the idealized demographic transition of a country. Include, written directly
onto the graph, an explanation for each change in the birth rate, death rate and total population
size.
