The Karner blue butterfly has been listed as an endangered species since 1992. Karner blue butterfly larvae feed only on wild lupine plants, which require a habitat with dry soil and exposure to direct sunlight.
Which of the following would be the best habitat for wild lupine that could help Karner blue butterfly populations recover?

a mountain top that is covered in snow

a river bank that was flooded by high water

an open area in a forest that was cleared by fire

an isolated area in a jungle that has many large trees

A large decrease in the sea otter population would most likely cause the size of which of the following populations to increase the most?

phytoplankton

barnacle

kelp

sea star

Which of the following statements best describes how an increase in the size of a mammal population could be related to a large surplus of food?

With an abundance of food, adults now outnumber predators.

With enough to eat, more females are healthy and the birth rate increases.

Since there is no competition for food, most individuals develop mutualistic relationships.

Since they no longer need to hunt, some males increase their territories and cause other males to move away.

The graph below shows the estimated number of orca whales off the coast of Washington State over a 20-year period
Which of the following best explains the orca population changes between 1996 and 2002?
