Big Ideas
- Ecosystem stability depends upon complex interactions among organisms and their environments.
- When environmental conditions change, these interactions may result in the formation of a new ecosystem.
Essential Questions
- How do complex interactions in ecosystems help maintain stability?
- What happens to the types and numbers of organisms when environmental conditions in an ecosystem change?
- How can evidence and reasoning be used to evaluate the stability of an ecosystem?
- What factors can disrupt the stability of an ecosystem and lead to the development of a new one?
- How do claims, evidence, and reasoning help us understand the dynamic nature of ecosystems?
