_{If the amount of food or resources available increases, the carrying capacity for an animal.....}

• Stays the same

• Increases

• Decreases

• Fluctuates

What point on the graph represents the carrying capacity?

• A

• B

• C

• D

When a population grows past the ecosystem's carrying capacity, what happens to the population?

• Continues to grow

• The population starts to die off to return to carrying capcity

• The population will go extinct due to lack of resources

• The population grows then finds a new carrying capacity
