1. Write a brief paragraph (3-5
sentences) regarding
Yellowstone wolves and elk.
Use the terms: keystone
species, apex predator, prey,
ecosystem, food web
Wolves are the keystone species and
apex predator of Yellowstone. Elk are
their prey. Wolves are necessary to
keep balance in the ecosystem because
they keep the elk population down,
allowing plants to grow. Plants provide
energy to many other organisms,
sustaining vital connections in the food
web.
