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.
