decrease
.

Answer 1

If the population of parasitic jaegers decreases, the population of rough-legged hawks will likely **increase**, and the population of short-tailed weasels will likely **decrease**.

This is because with fewer parasitic jaegers, there is less predation on rough-legged hawks, allowing their numbers to rise. Conversely, if rough-legged hawks increase in population, they may predate more on short-tailed weasels, leading to a decrease in their population.
