🌿 Help students understand how energy moves through ecosystems with this engaging Grade 7 Energy Flow Worksheet aligned with NGSS. This printable science resource introduces learners to the essential concepts of energy transfer through food chains, food webs, and energy pyramids. Students explore the roles of producers, consumers, and decomposers, investigate how energy enters ecosystems through photosynthesis, and discover why only a small portion of energy is transferred between trophic levels. Whether you're introducing ecosystem dynamics, reinforcing classroom instruction, or reviewing before assessments, this worksheet provides meaningful, standards-aligned practice.

📘 Why You'll Love This Resource

Energy flow is one of the most important concepts in life science because it explains how organisms survive and interact within ecosystems. This worksheet encourages students to analyze how energy moves from the Sun to producers and then through consumers and decomposers. Learners investigate the 10% energy transfer rule, compare food chains and food webs, and examine how changes in one organism can affect an entire ecosystem. Real-world examples help students connect scientific concepts to the natural world.
