Fact 1: Elk populations in Yellowstone National Park were overgrazing willow plants, leading to a significant decline in their numbers.
Fact 2: Wolves were reintroduced to Yellowstone, which resulted in a decrease in the elk population.
Observation: Following the reintroduction of wolves, the willow plant population began to recover over time.
Inference: The presence of wolves in the ecosystem creates a balance that allows for the regeneration of plant populations, indicating that apex predators play a crucial role in maintaining biodiversity.
