Instructions Use the passage and the graph below to answer the questions. PIELIPILLION Part I: Wolves of Yellowstone 2 1 point Categorize each of the events in the graph as a biotic or abiotic factor Although wolf packs once roamed from the Arctic tundra to Mexico hunting elk and other prey species, loss of habitat and extermination programs by humans led to their demise throughout most of the United States by early in the 1900s. In 1973, the US Fish and Wildlife Service listed the northern Rocky Mountain wolf (Canis lupus) as an endangered species and designated greater Yellowstone National Park as one of three recovery areas. From 1995 to 1997, 41 wild wolves from Canada and northwest Montana were released in Yellowstone National Park. As expected, wolves from the growing population dispersed to establish territories outside the park where they are less protected from human-caused mortalities. The park helps ensure the species' long-term viability in Greater Yellowstone and has provided a place for research on how wolves may affect many aspects of the ecosystem.
