Predation

Question 1

Parasitoids

Answer 1

Lay eggs on/near host and the larvae eventually eat it

Question 2

Parasites

Answer 2

Harm but don’t necessarily kill the host

Question 3

Doomed surplus

Answer 3

Predation on those likely to die anyways

Question 4

Ganse

Answer 4

Stable oscillations in the system are not a property of predator-prey interactions because complexity is a necessity

Question 5

Type 1 functional response

Answer 5

Straight line, no satiation

Question 6

Type 2 functional response

Answer 6

Saturation curve fixed by handling time

Question 7

Type 3 functional response

Answer 7

Sigmoid curve has a lag at low prey densities (learning curve)

Question 8

Max sustainable yields are no good because

Answer 8

K/2, smaller populations will be affected more, predation changes the habitat and pop characteristics of potential predators/competitors, no correlation is made for species interactions

Question 9

Tragedy of the Commons

Answer 9

A common resource being used by many = over exploitation

Question 10

Competitive Exclusion Principle

Answer 10

According to the principle of competitive exclusion, two similar species rarely occupy the same niche. Instead, they displace each other, taking possession of the foods and modes of life that give it an advantage of its competitors.
