Answer:
The number of ferrets will decrease.
Step-by-step explanation:
In communities, organisms occupy specific niches. These gradually evolve over time as these organisms interact with their geosphere. In each community, organisms maintain specific relationships among each other; these can be depicted within a food web.
Black-footed ferrets are typically found within prairies, and consume other small animals such as rodents. The removal of mice reduces their food supply, limiting their chance for survival. Thus, the ferret population would decrease due to migration, or death.
