David read about how wolves hunt in packs with specific roles for different pack members. He learned that wolf populations help control deer numbers in forests. His study of forest ecosystems showed how too many deer can damage young trees and plants. He also discovered that when wolves were removed from Yellowstone, the ecosystem changed dramatically.
By synthesizing this information, what new understanding can David develop about the role of predators in ecosystem balance?
- Wolves hunt in organized packs where different members have specific roles, and their presence helps control deer populations effectively in forest environments.
- Predators like wolves maintain ecosystem health by preventing herbivore overpopulation, which protects plant communities and maintains natural balance. (correct answer)
- When wolves were removed from Yellowstone, the ecosystem changed significantly because deer populations were no longer controlled by natural predation methods.
- Too many deer can damage young trees and plants in forests, while wolf populations help keep deer numbers at appropriate levels.
Explanation: Choice B synthesizes all information to develop new understanding about predators' role in ecosystem balance. The other choices combine only some facts without developing the broader insight about predator importance in maintaining ecosystem health.
