A. Population Biology Concepts1.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.PopulationTime
3.On the axes to the right, draw a line showing a population thatexemplifies logistic growth. (s-curve) and label the carryingcapacity.4.Perform the following calculation. Show all of your work. In aparticular year a population has the following characteristics:the crude birth rate is 45, the crude death rate is 20, theimmigration rate is 1%, and the emigration rate is 0.5%. Thepercent rate of growth for that year is __________.PopulationTimeShow work:45+10-20+5/100
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 andbiotic potential.
1.In what regions of the world is population density the greatest concern?How is populationdistribution 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 finalanswer.)1.A city has a population of 50,000 in 2012. If the population of the city grows at an annual rate of2%, the year in which the population will reach 100,000 is _____________ and the year it willreach 200,000 is _____________.Show work:
2.A country’s population was 12 million in 1992 and in 2012 it is 24 million. If the population grewat a constant rate, that percent rate of growth was _____________.Show work:
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 totalpopulation size during the idealized demographic transition of a country. Include, written directlyonto the graph, an explanation for each change in the birth rate, death rate and total populationsize.
