As food for a particular species becomes more scarce, often due to overpopulation of said species, it becomes harder for that species to survive. As such, their numbers dwindle. When this species gets to a low enough point, their food source starts to increase, because it's not being eaten as much. This allows the species to thrive, causing an influx of population. This cycle between predator and prey populations is what allows ecosystems to work.
