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

What is the carrying capacity of the graph?

around 500

more than 500

less than 500

around 600

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

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

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

What is a limiting factor?

Factors that always increase a population

Resources that are unlimited

Factors/resources that limit how many organisms can live in an area at the same time

If there was a wildfire in the forest that destroyed the plant life, what would happen to the herbivore population?

Herbivores would decrease due to a lack of food

Herbivores would increase due to an increase of food

Herbivores would not be affected

Herbivores would decrease due to an increase in predators
