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

• 3
• 7
• 70
• 40

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

• Density Independent limiting factors start to occur resulting in the population going farther above carrying capacity.
• Density Dependent limiting factors start to occur resulting in the population going back below carrying capacity.
• The population will go extinct due to lack of resources
• The population grows then finds a new carrying capacity

What is the carrying capacity of the graph?

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

What is the carrying capacity of the following graph?

• 1000
• 8000
• 800
• 600

Excessive amounts of rain caused a flood in the southwest United States that resulted in substantial amounts of deaths in the rabbit population? This situation is an example of a density _____________ limiting factor.

• density-independent
• density-dependent
• density- too high
• density- too low

A lion and a cheetah attempt to occupy the same niche. The more aggressive lion survives; the cheetah does not.

• Density-Dependent: Competition
• Density-Independent: Competition
• Density-Dependent: Predator-Prey
• Density-Independent: Predator-Prey

Since lynx prey on hares, an increase in the hare population causes an increase in the lynx population.

• Density-Dependent: Competition
• Density-Independent: Competition
• Density-Dependent: Predator-Prey
• Density-Independent: Predator-Prey

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.

What is the carrying capacity for this sheep population?

• 1.8 million
• 1.25 million
• 1.6 million
• 1.o million

What type of growth model is shown in image A?

• Exponential
• Logistic
