The graph to the right shows the interaction of the wolf and moose populations on Isle Pekie. If the moose population continues to increase, the wolves' food supply will increase. What will most likely happen to the wolf population as a result?

• It will decrease.

• It will increase.

• It will remain the same.

A scientist was studying a population of fish in a pond over a period of 10 years. He observed that

the population increased each year for 3 years, and then remained nearly constant for the rest of

the study. The best explanation for this observation is that the population had

• stopped reproducing

• reached carrying capacity

• mutated into a different species

• run out of food and all died

What happens if a population grows past its carrying capacity?

• The population keeps growing

• The population starts to die off

• The entire species will go extinct

• The carrying capacity just increases
