Predator/Prey

In the graph to the right, what is the population of deer at the carrying capacity of the environment?

• 3

• 7

• 70

• 40

What is the carrying capacity of the graph?

• around 500
• more than 500
• less than 500
• around 600

What will happen if all of the frogs in a population die?

• The frogs' predators will decrease and the frogs' prey will increase

• The frogs' predators will increase and the frogs' prey will decrease

• We better all pray because there isn't anymore frogs.

Food, water, sunlight, shelter, and space are resources that are  __________.

• limiting factors
• wet
• messy
• found in rocks

Which of the following would INCREASE the carrying capacity of an ecosystem?

• increase in predators
• disease
• increase in available food
• drought

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

• Stays the same

• Increases

• Decreases

• Fluctuates

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

According to the graph, what is causing the deer population to decrease

• They got sick

• The wolf population is decreasing

• The wolf population increased

• They ran out of food

Predator population lags behind prey population because......

• Increase in predators leads to decrease in prey

• Increase in predators leads to increase in prey

• Increase in predators leads to decrease in producers

• Increase in producers leads to increase in prey
