Respuesta :
Nature survives on a thin equilibrium between the species that hunt and those that are hunted.
When one of these increases or decreases drastically, the other is also affected.
In this case, both hawk and fox hunt mouses. If there's no mouses both hawk and the fox will starve to death.
The population of fox and hawk would decline if the population of mice reduced dramatically.
Population interaction
The populations of hawk and fox largely depend on the population of mice for their foods in the ecosystem.
If the population of mice declines significantly, it means that there would be a shortage of food for both hawk and fox populations.
Thus, famine will lead to a decline in the population of both organisms, all other things being equal.
