Explain how wolves can be used as a biological indicator of the overall health of the ecosystem?

Large carnivores in general are often used as indicator species because of their seat at the top of the food chain. When a large carnivore is missing from an ecosystem this can reflect problems in prey populations, usually caused by larger issues such as over-harvest of game, presence of disease, or habitat changes.
