♻️ Biodiversity and Balance
Explore what biodiversity means and why it matters for healthy ecosystems. Learn how different organisms depend on each other and what happens when species disappear from a community. **What you'll learn:** - Define biodiversity and identify examples in local ecosystems - Explain why ecosystems with many species are more stable - Recognize how losing one species affects food chains and habitats - Understand interconnections between plants, animals, and their environments
