It would increase a small amount since the insect population would decrease
It would decrease a lot because there is less to eat.
It would remain about the same since the finches would change to a different diet.
Mice produce a large number of offspring all year long, yet the number of mice within a given population changes very little from year to year. The stability of the population size is most likely the result of
mice continuing to reproduce when its population is large
the development of mutations in young mice
the survival of more female mice than male mice
limiting factors that keep the population in check
