Question 1

Which of the following situations illustrates a link between the effects of density-dependent and density-independent factors?

Accepted Answer

A) A flood causes a river to overflow and drown a herd of deer. 
B) A drought occurs;a small herd of deer is able to survive,whereas a larger herd in the same area perishes. 
C) A population of deer increases to a size at which individuals are competing with each other to get enough food. 
D) None of the above are correct because density-dependent and density-independent factors cannot affect the same population of organisms at the same time.

Question 2

The carrying capacity of owls in an Alaskan forest is seven per square kilometer.What will happen if twelve owls are confined to a 1-square-kilometer area?

Accepted Answer

A) The owls will survive together and develop ways to share resources. 
B) The owls might survive but the population size in the future will most likely be close to seven. 
C) The population of owl prey organisms will increase proportionately to support a larger population of owls. 
D) A short-term exponential growth of owls will occur because more mating pairs will form.

Question 4

A population of 10 yeast cells is put into a flask with growth media that contains all of the nutrients required for growth.The yeast has a doubling time of two hours;four hours after adding the yeast to the flask the population size is 40 cells.After three days the population size stabilizes at around 500 cells.Is this population exhibiting logistic or exponential growth? Explain your reasoning.

Accepted Answer

This population is exhibiting logistic g
