Owls and snakes eat mice and other organisms. What would happen to the mice population if the owl population decreased?

• The population would decrease, as the loss of owls as part of their diet is a limiting factor.

• The population would decrease, as shelters created by owl nests is a limiting factor.

• The population would increase, as competition for food is a limiting factor.

• The population would increase, as predation by owls is a limiting factor.
