Unit 3 - Population Ecology Test

What are the characteristics that population ecologists study?

• Geographic Range, Density and Distribution, Growth Rate, Age Structure

• Birth Rate, Death Rate, Immigration, Emigration

• Positive Growth Rate, Negative Growth Rate, Zero Growth Rate

• Exponential Growth, Logistic Growth, Carrying Capacity, Limiting Factors

What is the geographic range of a population?

• The number of individuals per unit area

• How individuals in a population aggregate or are spaced out

• The maximum number of individuals that an environment can support

• The area inhabited by a population

What is population density?

• The number of individuals per unit area

• How individuals in a population aggregate or are spaced out

• The maximum number of individuals that an environment can support

• The area inhabited by a population

What are the patterns of population distribution?

• Clumped, Uniform, Random

• Positive Growth, Negative Growth, Zero Growth

• Exponential Growth, Logistic Growth, Carrying Capacity

• Birth Rate, Death Rate, Immigration, Emigration

What is age structure?

• The number of individuals per unit area

• How individuals in a population aggregate or are spaced out

• The number of males and females of each age that a population contains

• The maximum number of individuals that an environment can support

What determines the growth rate of a population?

• Geographic Range, Density and Distribution, Growth Rate, Age Structure

• Birth Rate, Death Rate, Immigration, Emigration

• Positive Growth Rate, Negative Growth Rate, Zero Growth Rate

• Exponential Growth, Logistic Growth, Carrying Capacity, Limiting Factors

What is exponential growth?

• When a population grows faster and faster as time goes on

• When exponential growth slows down and eventually stops as it reaches carrying capacity

• The maximum number of individuals that an environment can support

• The number of males and females of each age that a population contains

What is carrying capacity?

• The number of individuals per unit area

• How individuals in a population aggregate or are spaced out

• The maximum number of individuals that an environment can support

• The area inhabited by a population

What is the term used to describe the period of exponential growth followed by a slowing and stopping of population growth?

• Exponential Growth

• Logistic Growth

• Density Dependent Growth

• Density Independent Growth

Which of the following factors can trigger logistic growth in a population?

• Birthrate and death rate

• Immigration and emigration

• Space and resources

• All of the above
