Common Mistakes to Watch For

• Thinking plants get their food from the soil instead of making it through photosynthesis using sunlight.
• Confusing food chains with food webs; a web shows many overlapping chains, not just one path of energy.
• Believing energy cycles like matter; actually, energy flows one way and is mostly lost as heat at each level.
