Examples of food chains in different ecosystems for kids

📚 Quick Study Guide

• ☀️ A food chain shows how energy passes from one living thing to another. It always starts with the sun!
• 🌱 Producers (like plants) make their own food using sunlight. This is called photosynthesis.
• 🌿 Consumers eat other organisms. There are herbivores (eat plants), carnivores (eat meat), and omnivores (eat both).
• 🦁 Each level in a food chain is called a trophic level. The first trophic level is always a producer.
• 🍄 Decomposers (like fungi and bacteria) break down dead organisms, returning nutrients to the soil.
• 🌊 An ecosystem is a community of living things interacting with each other and their environment. Examples include forests, oceans, and deserts.
• 🌍 Different ecosystems have different food chains depending on the available plants and animals.
