Population Growth Quiz

What is population growth?

• The decrease in the number of humans on Earth.

• The increase in the number of humans on Earth.

• The number of births that 1,000 women are expected to have.

• The total change in population from people moving in and out of the country.

Who are demographers?

• People who control population size.

• People who study the growth, density, and other characteristics of the population.

• People who predict the lifespan of individuals.

• People who manage food, water, and medical care.

Which of the following is NOT a major factor that affects population growth?

• Fertility rate.

• Life expectancy.

• Net immigration rate.

• Technological innovation.

What does the Fertility Rate indicate?

• The average lifespan a person is expected to reach.

• The total change in population from people moving in and out of the country.

• The number of births that 1,000 women are expected to go through in their lifetime.

• The average population size in a particular habitat.

What is the difference between exponential and logistic population growth?

• Exponential growth decreases over time, while logistic growth increases.

• Exponential growth is steady, while logistic growth has a "J" shape.

• Exponential growth increases upward with a "J" shape, while logistic growth increases and then flattens out, resulting in an "S" shape.

• Exponential growth is controlled by environmental factors, while logistic growth is not.

What are density independent factors?

• Factors that have an increasing effect on population growth as the density of the population increases.

• Factors that have a controlling effect on population size and growth, regardless of the population density.

• Factors that define the average population size in a particular habitat.

• Factors that are related to the number of births that 1,000 women are expected to have.

What is carrying capacity?

• The increase in the number of humans on Earth.

• The total change in population from people moving in and out of the country.

• The species' average population size in a particular habitat.

• The number of births that 1,000 women are expected to have.

If the number of births in a population is the same as the number of deaths in a population, what will happen to the growth of the population?

• It will increase.
• It will decrease.
• It will stay the same.
• It will fluctuate.

What growth pattern describes a population whose growth rate slows or stops following a period of exponential growth?

• logistic growth
• population growth
• exponential growth
• predator-prey cycle

What type of growth is shown in the diagram?

• exponential growth
• logistic growth 
• predator-prey cycle
• boom-bust curve
