This text explores the fundamental concepts of food chains, highlighting the roles of producers and consumers in ecosystems. Plants, as producers, harness sunlight for photosynthesis, creating energy that sustains life. Herbivores, the primary consumers, feed on these plants, while carnivores, the secondary consumers, rely on herbivores for energy. The document includes riddles to reinforce understanding by identifying whether given animals are producers or consumers. It encourages learners to think critically about food chains and create their own examples.
