· Question 1

3 out of 3 points

In a growing population, in the population growth model, as the population (N) gets close to the carrying capacity (K), the rate of population growth (dN/dt)

· Question 2

3 out of 3 points

In the population growth model, what happens to population size (N) if there is no constraint on growth?

· Question 3

3 out of 3 points

In the population growth model, dN/dt is a measure of ——————–.

· Question 4

3 out of 3 points

Consider Predator-Prey Model 1, in the plots of population versus time, what do the peaks in the prey population graph signify?

· Question 5

3 out of 3 points

In Predator-Prey Model 1, why are the predator and prey growth curves out of phase?

· Question 6

3 out of 3 points

In Predator-Prey Model 1, what causes the peaks in the prey population (i.e., what causes the prey population to stop increasing in size and start decreasing in size)?

· Question 7

3 out of 3 points

When the prey population is above the predator isocline, the predator population is:

· Question 8

3 out of 3 points

When the predator population is below the prey isocline, the prey population is:

· Question 9

3 out of 3 points

Given that the Predator-Prey Model 2 combines aspects of the Population Growth model and the Predator-Prey 1 model, can you determine what is causing the fluctuations? Can you figure out what causes the populations to eventually stabilize at zero population growth?

· Question 10

3 out of 3 points

In Predator-Prey Model 2, when a prey population dramatically decreases, the predator population will subsequently _______.
