materialization of precipitation

14.

In a logistic growth model the growth rate will be close to zero when...

a)

the population is close to carrying capacity

b)

the population starts growing quickly

c)

the population decreases due to a lack of food

d)

all of the above

the rate of growth

b)

the carrying capacity

c)

the size of the population

d)

the amount of time the population has been growing

16.

If the value of "r" in a population calculation is 0, that means that the population...

is not growing or declining

b)

is decreasing in size rapidly

c)

is beyond the carrying capacity

d)

will increase exponentially

17.

Which population will grow faster?

a)

Initial population of 2

b)

Initial population of 5

18.

Exponential growth cannot occur indefinitely (forever) on earth because all populations are limited at some point. What is the purpose of using exponential models?

a)

It allows us to see how a population could grow before it hits its carrying capacity

b)

It tells us what the carrying capacity of a population will be

c)

It shows us how bacteria could grow because bacteria populations are not limited

d)

It demonstrates how populations slowly change over time
