Help meh plz?

I say this because when the mice were living in this ecosystem they were consuming a lot of food . They also caused harm to the crops due to which the area had to be sprayed with pesticides . When this area is sprayed with pesticides the mice population will decrease thereby increasing he food supply of other grass eating animals like rabbit around them . This is why we say that when the mice population has decreased the rabbits' food supply would increase .
