• removal of predators

• removal of disease

The graph to the right shows the interaction of the wolf and moose populations on Isle Pekie. If the moose population continues to increase, the wolves' food supply will increase. What will most likely happen to the wolf population as a result?

• It will decrease.

• It will increase.

• It will remain the same.

What are factors that affect carrying capacity?

• Biotic only

• Biotic and abiotic

• Depends on the ecosystem

• Abiotic only

What type of growth is demonstrated in the graph?

• Exponential

• Carrying capacity

• Linear

• Negative

Exponential Growth occurs when-

• populations have plenty of food/space

• home to keystone species

• have few evasive species in a habitat

• have little to no competition or predators

Leveling off of the population after the maximum number the environment can support has been reached.

• Exponential

• Carrying capacity

• Linear

• Negative

Which of the following would likely be a limiting factor to a population?

• Abundance of food

• Living near a water source

• Presence of a natural predator

• Multiple sources for shelter

When rabbits were introduced to Australia, they began to breed exponentially. However, over time their population has begun to decrease due to a limiting factor. What is most likely the limiting factor in this situation?

• Abundant space to breed and live

• No available predator in the area

• Rabbits choosing not to mate to conserve space

• Lack of available food

Habitat availability increases for a population. How would the carrying capacity of the prey change?

• The carrying capacity would increase as more resources become available.

• Carrying capacity occurs independent of factors in the environment.

• The carrying capacity would decrease as more resources became available.

• The carrying capacity is set in an environment and cannot change.
