· 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 _______.
