Human Population Dynamics

What are some factors that affect human population dynamics?

• Birth and death rates

• Education and infant mortality

• Age of marriage and nutrition

• All of the above

What is an example of a density independent factor that can limit human population growth?

• Disease transmission

• Availability of food

• Wildfire

• Access to clean air and water

What is the role of education in human population dynamics?

• It affects fertility rates

• It affects infant mortality

• It affects the age of marriage

• All of the above

What is the doubling time of a population?

• The time it takes for a population to reach its carrying capacity

• The time it takes for a population to double in size

• The time it takes for a population to decline by half

• The time it takes for a population to stabilize

What is the rule of 70 used for?

• Calculating the doubling time of a population

• Calculating the growth rate of a population

• Calculating the carrying capacity of a population

• Calculating the mortality rate of a population

What is a density dependent factor that can limit human population growth?

• Territory size

• Heat wave

• Hurricanes

• All of the above

How does infant mortality affect human population growth?

• High infant mortality leads to population decline

• Low infant mortality leads to population decline

• High infant mortality leads to population growth

• Low infant mortality leads to population growth

What is the role of nutrition in human population dynamics?

• It affects fertility rates

• It affects infant mortality

• It affects the availability of food

• All of the above

What is the carrying capacity of a population?

• The maximum population size an environment can sustain

• The number of individuals in a population

• The rate at which a population is growing

• The number of resources available to a population

How can the doubling time of a population be calculated?

• Dividing 70 by the growth rate

• Multiplying 70 by the growth rate

• Adding 70 to the growth rate

• Subtracting 70 from the growth rate
