Predator Prey and Competition

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

• Stays the same

• Increases

• Decreases

• Fluctuates

What growth pattern describes a population whose growth rate slows or stops following a period of exponential growth?

• logistic growth
• population growth
• exponential growth
• predator-prey cycle

This is the largest number of individuals of a population that the environment can support...

• carrying capacity

• population crash

• lag phase

• mutualism

Which type of growth is best illustrated by this rabbit population?

• exponential

• logistic

• S-shaped

• predator-prey

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

How will competition affect the carrying capacity of an ecosystem for the animal in competition?

• Decrease
• Increase
• Will show not affect
• Competition does not exist in nature

In a forest ecosystem, which of the following is the best example of a limiting factor for a rabbit population?
