15.

Scientists have been studying the size of three populations along the coast of Antarctica. In this ecosystem, penguins eat sardines (a type of small fish), and sardines eat zooplankton (very small animals that live in water). The data showed that all three populations were stable. Then the penguin population decreased suddenly.


What will likely happen to the size of the sardine population as a result?

a)

stay the same. The size of its resource population did not change, so the amount of energy storage molecules available for the sardines did not change. There will be the same number of births and deaths in the sardine population.

b)

decrease. A decrease in one population causes a decrease in the sizes of all other populations in the ecosystem.

c)

increase. The smaller penguin population will leave more energy storage molecules available for the sardine population to reproduce more. This will lead to more births in the sardine population.

d)

increase. The smaller penguin population will need fewer energy storage molecules, so they will eat fewer sardines. This will lead to fewer deaths than births in the sardine population.

16.

Scientists have been studying the size of three populations in a grassland. In this ecosystem, snakes eat rats, and rats eat grasshoppers. The data showed that all three populations were stable. Then the grasshopper population decreased suddenly. What will likely happen to the size of the rat population as a result?

a)

stay the same. The size of their consumer population did not change, so the number of deaths in the rat population did not change. There will be the same number of births and deaths in the rat population.

b)

increase. The smaller grasshopper population will need fewer energy storage molecules so there will be more energy storage molecules available for the rat population to reproduce. This will lead to more births in the rat population.

c)

decrease. A decrease in any population leads to a decrease in the sizes of all other populations in the ecosystem.

d)

decrease. The smaller grasshopper population provides fewer energy storage molecules for the rat population, so the rat population will reproduce less. This will lead to fewer births than deaths in the rat population.
