Scientists are studying how wolves have shaped the ecosystem in Yellowstone National Park in Wyoming. They have found that an increase in wolf populations affects the populations of so many other living things that the rivers and mountains actually changed as well. In what branch of biology do these scientists work?

• Ecology

• Botany

• Cell biology

• Anatomy and Physiology
