Question 1

which is a nonrenewable resource?

Answer 1

space

Question 2

T/F water is a nonrenewable resource?

Answer 2

FALSE

Question 3

How is Liebig’s law of the minimum related to a population’s growth?

Answer 3

it states that a population increases until the most limiting resource prevents further increase

Question 4

If two species require the same limiting resource, what would you predict about their ability to coexist?

Answer 4

They will be unable to coexist whether the resource is renewable or nonrenewable.

Question 5

why are population growth rates at zero when two species are at equilibrium?

Answer 5

at equilibrium both species have reached carrying capacity

Question 6

Why do closely related species often experience more intense competition than distantly related species?

Answer 6

Closely related species are more likely to rely on the same limiting resource.

Question 7

exploitative competition

Answer 7

causes the abundance of a resource to fall lower than other species can use

Question 8

explain the concept of “competition coefficients” that are used in the Lotka-Volterra competition equations

Answer 8

they convert the number of individuals b/w 2 competing species

Question 9

why is allelopathy considered a form of interference competition?

Answer 9

it allows a species to prevent its competitors from competing effectively

Question 10

under what conditions can two species competing for two resources coexist?

Answer 10

when each species can persist at lower level of one resource

Question 11

apparent competition

Answer 11

occurs when two species have a negative effect on each other through an enemy
