Worksheet 5: Population ecology 2 – Population Growth

Plagiarism is unacceptable and will result in an automatic 0 on this assignment.

Section 1: Type 1 Functional Response

Question 1: Briefly describe a type one functional response. What is the relationship between

prey density and intake rate of a consumer? What assumptions are made (hint recall for type 1

Th=0)? (2 points)

Question 2: Please insert graph you made showing the number of prey eaten vs number of prey

available, for both expected prey eaten (Pe) values, and average Prey eaten values in your

simulation. (Please make sure that you have included best fit line for both series and that your

axes are properly labeled. Etc…) (4 points)

Question 3: Did your simulated Pe values match what you might expect for a type one functional

response? Why or why not? (2 points)

Question 4: Did your simulated (average) Pe values differ greatly from your predicted Pe values

generated using the Holling Disc equation? If it differed how did it do so? Why do you think this

might be? (2 points)

Section 2: Type 2 functional response

Question 1: Briefly describe a type two functional response. What is the relationship between

prey density and intake rate of a consumer? What assumptions are made? (2 points)

Question 2: Please insert graph you made showing the number of prey eaten vs number of prey

available, for both expected prey eaten (Pe) values, and average Prey eaten values in your

simulation. (Please make sure that you have included best fit line for both series and that your

axes are properly labeled. Etc…) (4 points)

Question 3: Did your simulated Pe values match what you might expect for a type two

functional response? Why or why not? (2 points)

Question 4: Did your simulated (average) Pe values differ greatly from your predicted Pe values

generated using the Holling Disc equation? If it differed how did it do so? Why do you think this

might be? (2 points)

Section 3: Type 3 functional response (Extra Credit)

Question 1: Briefly describe a type three functional response. What is the relationship between

prey density and intake rate of a consumer? (1 point)

Question 2: If you wanted to simulate a type three functional response using candy/snacks and

people in a manner similar to how we simulated the other types of functional responses today,

how might you go about it? (1 point)
