Multiple Choice

Describes how the organisms are spread out from one another.

• Denisty

Multiple Choice

Three factors can affect population size

• births, deaths,immigrant or emmigrant

• deaths, birth, buildings

Multiple Choice

Which population has abundant resources?

Multiple Choice

Exponential population growth can be described as

• growth when resources are limited

• a j-shaped curve

• a s-shaped curve

• growth that reaches carrying capacity

Multiple Choice

Logistic population growth can be described as

• growth when resources are limited

• a s-shaped curve

• reaching carrying capacity

• all of the above

• none of the above

Multiple Choice

• 250

• 1000

• 400

• 720

Multiple Choice

If the amount of food or resources available increases, the carrying capacity for an animal:

• Stays the same
• Increases
• Decreases
• Fluctuates

Multiple Choice

Any factor(s) that controls/ limits the size of a population.

• Density dependent limiting factors

• Limiting factors

• Density independent limiting factors

• Environmental Resistance

Multiple Choice

Which of the following would be an example of a density independent limiting factor?

• fire

• disease

• lack of food

• space

Multiple Choice

• Density-Dependent: Competition

• Density-Independent: Competition

• Density-Dependent: Predator-Prey

• Density-Independent: Predator-Prey
