Limiting Factors to Population

Limiting Factors

A factor that causes population growth to decrease (get smaller).

Density dependent limiting factors

A limiting factor that depends on population size. They become limiting when the number of individuals reach a certain number. This only occurs in large and densely populated areas.

Human Activities

Building dams and cutting down the rainforest.

Examples of limiting factors

Competition, Predation, Parasitism and disease, Drought and other climate changes, and Human disturbances.

Examples of density dependent limiting factors

Competition, predation, parasitism, and disease.

Unusual weather

Drought and flooding.

Natural disasters

Earthquakes and the black plague.

Predator

Eats other individuals.

Seasonal Cycles

Extreme heat and severe frost.

Prey

Gets eaten by other individuals.

If the Lynx population disappears, what would happen to the rabbit population?

Increase.

Density independent limiting factors

Limiting factors that affect ALL populations, regardless of size.

Predator-Prey relationship

One of the best ways to control population.

Competition is

Other individuals in a species.

Examples of density independent limiting factors

Unusual Weather, natural disasters, seasonal cycles, and human activities.
