Population Limiting Factors

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

Natural disasters can be considered limiting factors.

• true: they are density independent limiting factors

• true: they are density dependent limiting factors

Limiting factors which impact the size of a population no matter how large that population is.

• Density Independent Limiting Factors
• Density Dependent Limiting Factors
• Carrying Capacity
• Exponential Growth

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

Coyotes cross the winter pack ice and enter Newfoundland. The moose population starts to decline.

• Density-Dependent: Pedator-Prey

• Density-Independent: Competition

A severe flood in the Red River Valley causes a decline in the deer population.

• Density-Dependent

• Density-Independent

Which is NOT an example of a limiting factor.

• Climate
• Available Food & Water
• Available Space & Shelter
• Species color

Environmental factors that keep a population from increasing. 

• Carrying Capacity
• Limiting Factors

The largest number of organisms that the environment can support. 

• Carrying Capacity
• Limiting Factor

Occurs when part of the population LEAVES the environment

• Immigration
• Emmigration
