Elk in Yellowstone National Park were overgrazing the willow plant populations. Wolves were reintroduced and the willow plant population recovered. In three to five sentences, state two facts, make an observation, and make an inference.(4 points)

Answer 1

Fact 1: Elk populations in Yellowstone National Park can overgraze willow plants, leading to a decline in their numbers.
Fact 2: The reintroduction of wolves into the ecosystem helped to control the elk population, allowing willow plants to recover.
Observation: The presence of wolves has led to a noticeable increase in willow populations in areas where elk are less frequent.
Inference: The reintroduction of wolves not only affects elk behavior but also plays a crucial role in restoring and maintaining the health of the ecosystem by supporting the growth of plant species like willow.
