5the main predators of field mice in a certain ecosystem are rattlesnakes and foxes. suppose humans begin building neighborhoods in the ecosystem, driving out many of the indigenous rattlesnakes and foxes. what will most likely happen to the field mice's population?

The population of the mice would most likely increase. This is because the number of predators of mice will decrease. Predators are those that feed on others, in this case mice. When predators decrease, the prey (which would be the mice) will be able to populate thus leading to an increase in population.
