Scientists have been studying the size of three populations in a grassland. In this ecosystem, lizards eat fireflies, and fireflies eat gnats (a type of insect). The data showed that all three populations were stable. Then the lizard population decreased suddenly. What will most likely happen to the size of the firefly population as a result?

• increase because there are less lizards eating them.

• decrease because there are more lizards eating them.

• stay the same

• increase because there will be more energy storage molecules available for the fireflies to eat.

In Australia, both opossums and foxes eat rats. The sizes of the populations have been stable for the last 12 years, but recently the size of the opossum population increased. What will likely happen to the fox population?

• increase because there will be more rats to make energy.

• decrease because the opossum population is taking more energy storage molecules from the rats.

• stay the same because there are still energy storage molecules available.

• decrease because the opossum population is using the fox population for energy storage molecules.

Scientists have been studying the size of three populations in a region. In this ecosystem, lions eat wild pigs, and wild pigs eat frogs. The data showed that all three populations were stable. Then the frog population decreased suddenly. What will likely happen to the size of the wild pig population as a result? The size of the wild pig population will . . .

• increase because the wild pigs and lions will find energy storage molecules elsewhere.

• decrease because there are less energy storage molecules available.

• stay the same because the lions are still stable.

Scientists have been studying the size of three populations in a swampland. In this ecosystem, herons (a type of bird) eat frogs, and frogs eat dragonflies. The data showed that all three populations were stable. Then the dragonfly population increased suddenly. What will likely happen to the frog population as a result? The size of the frog population will . . .

Scientists have been studying the size of three populations in Peru. In this ecosystem, pumas (large wild cats) eat deer, and deer eat grass. The data showed that all three populations were stable. Then the puma population increased suddenly. What will most likely happen to the size of the deer population as a result? The size of the deer population will . . .

• increase
