Ecological Limiting Factors

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

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

• Stays the same
• Increases
• Decreases
• Fluctuates

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

• density-independent

• density-dependent

• density- too high

• density- too low

An environmental factor such as storms and extreme heat or cold that decrease a population are considered to be. 

• density- dependent factor
• population density
• dispersion
• density- independent factor

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

• Density-Dependent: Competition

• Density-Independent: Competition

• Density-Dependent: Predator-Prey

• Density-Independent: Predator-Prey

• Density-Dependent: Disease

• Density-Independent: Disease

Since owls prey on mice, an increase in the mice population causes an increase in the owl population.

• Density-Dependent: Competition

• Density-Independent: Competition

• Density-Dependent: Predator-Prey

• Density-Independent: Predator-Prey
