4. What are four density-dependent limiting factors?

5. When populations become crowded, what do organisms compete with one another for?

6. The mechanism of population control in which a population is regulated by predation is called a (an)

_____________________________________.

7. What are the prey and what are the predators in the predator-prey relationship on Isle Royale?

8. Why does the wolf population on Isle Royale decline following a decline in the moose population?

Density-Independent Factor

1. A limiting factor that affects all populations in similar ways, regardless of population size, is called a

(an) _____________________________________.

2. What are examples of density-independent limiting factors?

3. What is the characteristics response in the population size of many species to a density-independent

limiting factor?
