Age Structure and Survivorship Simulation
Question 1 of 4
Activity 54.4 Quiz
Study the age structures and their corresponding survivorship curves below. They represent different populations of a bear species, a mosquito species, and a pelican species.
Match each age structure to its survivorship type and organism. Use the simulation to test your prediction before committing to one of the four options below.
A.
B.
C.
D.
Correct. See Key Concept 54.2 Population Growth Describes the Change in Population Size over Time
Incorrect. See Key Concept 54.2 Population Growth Describes the Change in Population Size over Time
Activity 54.4 Quiz
Study the two age structures below. They both represent the same population at different times in the population’s history.
What factor could have been responsible for the changes in the population’s age structure? Use the simulation to test your prediction before committing to one of the four options below.
A.
B.
C.
D.
Correct. See Key Concept 54.2 Population Growth Describes the Change in Population Size over Time
Incorrect. See Key Concept 54.2 Population Growth Describes the Change in Population Size over Time
Activity 54.4 Quiz
Study the age structure for a human population below.
How do you predict that an increase in emigration will change the shape of this population’s age structure? Use the simulation to test your prediction before committing to one of the four options below.
A.
B.
C.
D.
Correct. See Key Concept 54.2 Population Growth Describes the Change in Population Size over Time
Incorrect. See Key Concept 54.2 Population Growth Describes the Change in Population Size over Time
Activity 54.4 Quiz
Study the two age structures below. One represents a population of mice and the other represents a population of wolves. Both populations are present in the same ecosystem.
Identify each population and explain which is predicted to be most vulnerable to increases in predation on their offspring? Use the simulation to test your prediction before committing to one of the four options below. When running your test, it will be important that you select the appropriate survivorship type for each mammal.
A.
