Population Dynamics Checkpoint

Check exponential growth, logistic growth, carrying capacity, and model limitations.

Scenario

An ecologist compares an ideal population model with a habitat whose resources and disturbances can change.

Scored questions

Question 1

Which equation includes density-dependent slowing near carrying capacity?

Question 2

For N = 200, r = 0.10 per year, and K = 1000, what is dN/dt in the logistic model?

Question 3

Which statement about carrying capacity is most accurate?

Question 4

When N is very small relative to K, the logistic model initially behaves most like:
