Owls and mice have a predator/prey relationship. Owls are the predators, and mice are the prey. What happens to the mouse population when there is a decrease in the owl population?

When there is a decrease in the owl population, it can have a positive effect on the mouse population. With fewer predators, the mice may experience a decrease in predation pressure, resulting in an increase in their population size. The reduced presence of owls may decrease the mortality rate of mice due to predation, allowing them to reproduce more successfully and thrive. Consequently, the mouse population might increase in numbers or expand into new areas with less fear of predation.
