A Moose on Isle Royale (IMAGE) Michigan Technological University Caption An adult moose must eat approximately 40 pounds of vegetation per day just to keep itself going. Yet despite their need to consume large volumes of food every day, moose do not eat everything they come across. Instead, moose are considerably more selective than is obvious when deciding which plant species to eat. Credit Sarah Hoy/Michigan Tech Usage Restrictions Please credit the photographer.
