The common fox regulates the number of forest mouse-like rodents. How will the state of the inhabitants of the forest biocenosis change with complete extermination or a sharp reduction in the number of foxes?
1) First, the number of mouse-like rodents will increase sharply, because there are no predators.
2) Then it will begin to decline, under the influence of diseases and parasites, because they will destroy their food supply — competition will increase (and also predators will destroy sick and weakened animals).
