A student claims that a firefly population experienced a change that made it impossible for the insects to flash their lights. Which of these changes would support the student’s claim?
The population would increase, because predators could no longer see the fireflies to catch them as prey.
The population would decrease, because the male fireflies could not attract mates without their lights.
The population would increase, because more fireflies would move into the unlit area, thinking it was empty.
The population would decrease, because prey for the fireflies would no longer be able to see their lights.
If the population of Species 1 decreased, what would most likely happen first to Species 2?
Species 2 would increase in number.
Species 2 would decrease in number.
Species 2 would become extinct.

In which two ways can this model represent the Coriolis effect?
