This document discusses the characteristics, habitat, food sources, predators, and effects of humans on wolves. It notes that wolves hunt in packs, howl, are furry and strong mammals that live in North America, South America, Europe, and North Asia. They are omnivores that hunt other animals like moose but also have predators such as humans and bears. Their habitat is shared with other animals like foxes, beavers, bears, coyotes and moose. Humans can negatively impact wolves' habitat by cutting trees, hunting their prey, and ruining forests. Losing members of the food chain, like moose, could also affect wolves.
