Population Growth

At what population was carrying capacity met?

• 250

• 1000

• 400

• 720

The largest number of individuals that an environment can support long term is...

• carrying capacity

• emigration

• immigration

• population density

What happens if a population grows past its carrying capacity?

• The population keeps growing

• The population starts to die off

• The entire species will go extinct

• The carrying capacity just increases

This may cause a population to increase

• increase of food supply

• removal of predators

• removal of disease

• all of these

Something that regulates the size of a population is called...

• a limiting measure

• a limiting factor

• carrying capacity

• biodiversity

What is the carrying capacity of the graph?

• around 500

• more than 800

• less than 300

• around 700

• The bird population would infinitely increase
• The bird population would decrease

If the number of births in a population is the same as the number of deaths in a population, what will happen to the growth of the population?

• It will increase.
• It will decrease.
• It will stay the same.
• It will fluctuate.

If the number of births is greater than the number of deaths in a population, what will happen to the growth of the population?

• It will increase.
• It will decrease.
