How might the size of a sea urchin affect the sea otters' choice of prey?

• Otters would not prefer the larger prey, because it would take too long to eat

• Otters would prefer the larger prey, because they provide more energy.

• Otters would prefer smaller prey, because they are easier to digest

• Otters would have no preference based on size

Based on the data from the graph, how do the otters impact the two species of sea urchins?

• By eating more purple sea urchin, this population is decreased the most.

• By eating more red sea urchin, this population is decreased the most.

• By eating the same number of both species, the two populations decrease the same.

• Otters do not impact sea urchin populations.

What do you think would happen to the average sea urchin size if the sea otters in (B) were removed?

• The average size of sea urchins would increase

• The average size of sea urchins would decrease

• The average size of sea urchins would stay the same

• The average size of sea urchins would not be affected

Relative sea urchin size (diameter in cm) in an area without sea otters (A) and an area with sea otters (B). Based on the evidence from the graph, why are sea otters considered a keystone species?

• They eat all of the small urchins to keep them from overpopulating

• They eat the medium to larger sea urchins to keep the population in balance

• They are eaten by the sea urchins for energy.

• Sea otters do not eat sea urchins.
