Leveling off of the population after the maximum number the environment can support has been reached.

• Exponential

• Carrying capacity

• Linear

• Negative

Habitat availability increases for a population. How would the carrying capacity of the prey change?

• The carrying capacity would increase as more resources become available.

• Carrying capacity occurs independent of factors in the environment.

• The carrying capacity would decrease as more resources became available.

• The carrying capacity is set in an environment and cannot change.

When Yellowstone National Park was created in the late 1800s, wolves were on the decline. The last wolves in Yellowstone were killed in 1926, but in the 1800s, there were between 100-160 wolves in the park. In 1995, gray wolves were reintroduced to the park.

Which graph (drawn in red) below shows a prediction of how the population would change if there was less water available in the ecosystem?

• 
• 
• 
• There would be no change to carrying capacity.
