13. Scientists have been studying the size of three populations in a river in Ireland. In this ecosystem, pike (a type of big fish) eat perch (a type of small
fish), and perch eat snails. The data showed that all three populations were
stable. Then the snail population increased suddenly. What will likely happen
to the size of the perch population as a result?
