What is the carrying capacity of the following graph?

• 1000

• 8000

• 800

• 600

Answer explanation

The carrying capacity of the graph is 1000, as it represents the maximum population size that the environment can sustain indefinitely.

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

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

Answer explanation

The excessive rain causing a flood and resulting in deaths in the rabbit population is an example of a density-independent limiting factor because it is not influenced by the population size.

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

Answer explanation

Density Independent Limiting Factors are the limiting factors that impact population size regardless of its size, making them the correct choice in this scenario.

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

Answer explanation

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

Factors that limit the growth of a population are called?

• Carrying Capacity

• Limiting Factors

Answer explanation

Factors that limit the growth of a population are called Limiting Factors.

If a disease destroying barley plants in a field swept through an ecosystem, what would happen to the barley eating bird population in the the field ?

• The bird population would stay the same

• The bird population would infinitely increase

• The bird population would decrease

Answer explanation

If a disease destroys barley plants, the food source for barley-eating birds decreases, leading to a decrease in the bird population.
