🕸️ Food Webs
Explore the interconnected feeding relationships in ecosystems through food webs. Unlike linear food chains, food webs show how multiple organisms depend on each other in overlapping paths. Discover which plants and animals are connected, and understand why ecosystems stay balanced when different feeding routes exist. **What you'll learn:** - How food webs connect multiple food chains in one ecosystem - How to identify which organisms depend on which for food - Why ecosystems need many different feeding relationships to survive
