As a population of a species increases within a territory, which of the following most likely also increases?

• Immigration

• Food supply

• Carrying capacity

• Competition

If a population grows larger than its environmental carrying capacity, then

• death rate may rise.

• death rate may fall significantly.

• birth rate may rise significantly.

• immigration rate may increase.

What does the term carrying capacity describe?

• The maximum number of birth rates for a population.

• The ability of a population to accept new immigrants.

When a population grows past the ecosystem's carrying capacity, what happens to the population?

• Continues to grow
• The population starts to die off to return to carrying capcity
• The population will go extinct due to lack of resources
• The population grows then finds a new carrying capacity
