🕸️ Food Webs and Networks
Explore the interconnected relationships in ecosystems through food webs! Unlike simple food chains, food webs show how organisms have multiple feeding relationships, making them more realistic models of energy flow in nature. You'll learn to identify producers, consumers, and decomposers; trace energy pathways; and understand why food webs better represent how ecosystems actually work. **What you'll learn:** - How food webs differ from food chains - How to identify feeding relationships and energy flow - Why food webs are more realistic ecosystem models - How to trace multiple pathways in a food web
