Carrying capacity refers to:

• The total number of species in an area

• The average number of individuals in an area

• The minimum number of individuals an area can support

• The maximum number of individuals an area can support

What happens to a population when it exceeds its carrying capacity?

• It stabilizes

• It declines

• It continues to grow

• It remains unchanged

In a carrying capacity graph, what typically happens after a population overshoots its carrying capacity?

• The population stabilizes immediately

• The population continues to grow

• The population drops below carrying capacity

• The population remains constant

What effect do predators have on the population of their prey?

• Increase the prey population

• Decrease the prey population

• Have no effect on the prey population

• Cause the prey population to fluctuate randomly
