1. Coyotes as one of the most adaptable canine animals can be found in Deserts, prairies, woodlands, open pine forests and much more. The ecosystem would have the prey they eat such as Deer, Rabbits, Rodents, Fish, and Frogs.
2. If the number of coyotes was to change dramatically there would be less prey left not for only the coyotes but other predators of those prey. Not to mention the predators of the coyotes. The ecosystem would soon be destroyed.
3. The number of prey would go up much and the predators of the coyotes would either starve or have to adapt and eat the coyote's prey which depending on the species some couldn't.
