What will most likely happen to the size of the firefly population if the lizard population decreased suddenly?
The firefly population will increase. The smaller lizard population will need fewer energy storage molecules so they will eat fewer fireflies. This will lead to fewer deaths than births in the firefly population.
The firefly population will increase. The smaller lizard population will leave more energy storage molecules available for the firefly population to reproduce more. This will lead to more births in the firefly population.
The firefly population will stay the same. The size of its resource population did not change, so the amount of energy storage molecules available for the fireflies did not change. There will be the same number of births and deaths in the firefly population.
The firefly population will decrease. A decrease in any population causes a decrease in the sizes of all other populations in the ecosystem.

What will likely happen to the fox population if the size of the opossum population increased in Australia?
The size of the fox population will increase. An increase in the size of any population leads to an increase in the sizes of all other populations in an ecosystem.
The size of the fox population will stay the same. Opossums and foxes do not eat each other, so the number of births and deaths in the fox population will stay the same.
The size of the fox population will decrease. The larger opossum population will leave fewer energy storage molecules for all other populations in the ecosystem, so the fox population will reproduce less. This will lead to fewer births than deaths in the fox population.
The size of the fox population will decrease. Fewer energy storage molecules will be available to the fox population from the smaller rat population, so the fox population will reproduce less. This will lead to fewer births than deaths in the fox population.

What will likely happen to the size of the wild pig population if the frog population decreased suddenly?
The size of the wild pig population will increase. The smaller frog population will need fewer energy storage molecules so there will be more energy storage molecules available to the wild pig population. This will lead to more births in the wild pig population.
The size of the wild pig population will decrease. The smaller frog population will provide fewer energy storage molecules for the wild pig population, so the wild pig population will reproduce less. This will lead to fewer births than deaths in the wild pig population.
The size of the wild pig population will decrease. A decrease in any population causes a decrease in the sizes of all other populations in an ecosystem.
The size of the wild pig population will stay the same. The size of their consumer population did not change, so the number of deaths in the wild pig population did not change. There will be the same number of births and deaths in the wild pig population.

What will likely happen to the shark population if the size of the crab population increased in the Arctic Ocean?
The size of the shark population will decrease. The larger crab population will leave fewer energy storage molecules available in the ecosystem for the shark population, so there would be fewer births in the shark population.
The size of the shark population will increase. An increase in the size of any population leads to an increase in the sizes of all other populations in an ecosystem.
The size of the shark population will increase. More energy storage molecules will be available to the shark population from the larger whale population, so the shark population will reproduce more. This will lead to more births than deaths in the shark population.
The size of the shark population will stay the same. Sharks do not eat crabs, so the number of births and deaths in the shark population will stay the same.

Humans started protecting the duck population so they stopped dying.
The ducks did not have any baby ducks during these years.
