Answer:
a disease which infects the baby mice shortly after birth.
Explanation:
In the given scenario if adequate resources are available population growth occurs rapidly. For example one female mouse can produce a litter of four to fourteen babies every three to four weeks throughout her life.
However if there is a factor unrelated to the resources such as food and space it could limit growth rate.
A disease which infects the baby mice shortly after birth will effectively keep rapid growth rate in check
