Remora fish can attach themselves to larger aquatic animals, such as whales. When the whales eat, the fish detach themselves and eat leftover scraps of food. These fish do not harm or help the whales.
What is the ecological relationship between the remora fish and the whales?

competition

commensalism

parasitism

predation

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 number of orcas born was less than the number of orcas that died.

The number of orcas emigrating was higher than the number of orcas immigrating.

The total number of orca births and immigrants was more than the total number of orca deaths and emigrants.

The total number of orca births and deaths was greater than the total number of orca immigrants and emigrants.
