⚡ Energy Flow: Food Chains
Explore how energy moves through ecosystems! This quiz covers food chains, trophic levels, and the roles of producers and consumers. You'll learn to identify organisms at each level, trace energy transfer, and understand why energy decreases as it moves up the food chain. **What you'll learn:** - How to identify producers, consumers, and decomposers in food chains - The role of trophic levels in energy transfer - Why energy decreases at each level of a food chain - How to construct and interpret simple food chains - The difference between primary, secondary, and tertiary consumers
