Examples of Simple Food Chains for Elementary

📚 Quick Study Guide

• 🌱 A food chain shows how energy passes from one living thing to another.
• ☀️ All food chains start with the sun. Plants use the sun's energy to make their own food through a process called photosynthesis.
• 🌿 Producers (like plants) are at the bottom of the food chain.
• 🐛 Consumers eat the producers (primary consumers), and then other consumers eat those consumers (secondary and tertiary consumers).
• 🦊 Decomposers (like fungi and bacteria) break down dead plants and animals, returning nutrients to the soil.
• 🌍 A simple food chain example: Grass $\rightarrow$ Grasshopper $\rightarrow$ Frog $\rightarrow$ Snake.
• 💡 Energy decreases as you go up the food chain.
