Predation and Herbivory

Question 1

Lotka-Volterra Predator/Prey Model

Answer 1

a model of predator-prey interactions that incorporate oscillations in predator and prey populations. it shows predator numbers lagging behind prey

Question 2

Functional response

Answer 2

the relationship between density of prey and an individual predator’s rate of food consumption

Question 3

Numerical response

Answer 3

the change in the number of predators as a function of change in prey density

Question 4

Type I functional response

Answer 4

when a predator’s rate of prey consumption increases in a linear fashion with an increase in prey density

Question 5

Type II functional response

Answer 5

when a predator’s rate of prey consumption begins to slow as prey density increases and then plateaus.

Question 6

Type III functional response

Answer 6

when a predator exhibits low, rapid and slowing prey consumption under low, moderate, and high prey densities

Question 7

Avoidance

Answer 7

hiding (ex: armadillo)

Question 8

Crypsis

Answer 8

blending in with their surroundings

Question 9

Structural defense

Answer 9

structures for protection (ex: porcupine)

Question 10

Mimicry

Answer 10

resembling other species

Question 11

Chemical defense

Answer 11

chemical protection (ex: skunk)

Question 12

Aposematism

Answer 12

warning coloration.

Question 13

Batesian mimicry

Answer 13

species evolve warning coloration that matches dangerous species

Question 14

Mullerian mimicry

Answer 14

several species evolve a similar pattern of warning coloration

Question 15

Coevolution

Answer 15

two or more species affect each other’s evolution
