Pandas depend on bamboo. The amount of intact bamboo forest will help determine the:

• Biotic potential of the species

• Carrying capacity of the environment

• Rate of emigration

A population crash occurs when:

• Resources are essentially unlimited

• A population overshoots (goes past) its carrying capacity

Using the graph, which of the following is most likely reason for the change in the moose population between 1995 and 1997?

• The increase in wolf population

• A severe winter in 1995 caused many moose to die from exposure to cold

• The high population density of moose eliminated their food
