Need to look at material and fill this in again.

Question 3

Type I Functional Responses

Answer 3

Predator consumes a constant proportion of prey until satiated.

Question 4

Type II Functional Responses

Answer 4

Predator consumes a decreasing proportion of prey as prey numbers increase

Question 5

Type III Functional Responses

Answer 5

Predators consume an increasing proportion of prey in low densities, then decreasing in higher prey densities.

Question 6
