Carrying Capacity Pt 1

What is the carrying capacity of the graph?

• 1000

• 8000

• 800

• 600

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

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

• carrying capacity

• emigration

• immigration

• population density

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

Which of the following would INCREASE the carrying capacity of an ecosystem?

• increase in predators
• disease
• increase in available food
• drought

When death rate is equal to birth rate...

• population increases

• population decreases

• population stays the same.

• population rapidly increases then becomes stable

When the death rate rises and the birth rate lowers...

• population increases

• population decreases

• population stays the same

• all of these

When birth rate is high and death rate is low...

• population increases

• population decreases

• population stays the same

• all of these
