🌿 Grade 7 Science Worksheet – Matter & Energy Flow (California Standards)
Help students master how energy and matter move through ecosystems with this engaging, standards-aligned worksheet. Designed for middle school science learners, this resource clearly explains how producers, consumers, and decomposers interact within food chains and food webs while reinforcing the concept that energy flows while matter cycles.

🔬 What’s Included in This Resource
• Informational reading passage on energy and matter flow in ecosystems
• 15 multiple-choice questions for comprehension and application
• 18 true/false questions to reinforce key concepts
• 5 short-answer questions for deeper scientific explanation
• Word bank matching activity for vocabulary support
• 2 extended response essay prompts for critical thinking
• Student notes lines for structured learning support
• Answer key included (separate PDF for easy grading)

⚡ Key Science Concepts Covered
• Role of producers, consumers, and decomposers in ecosystems
• Energy transfer through food chains and food webs
• How sunlight is converted into chemical energy
• Why energy decreases at each trophic level (heat loss during metabolism)
• Recycling of matter through decomposers and nutrient cycles
• Interconnected relationships in ecosystem food webs

🧠 Student Learning Outcomes
This worksheet helps students develop a strong understanding of how ecosystems function. Students will:
• Explain how energy flows from the Sun through organisms
• Describe how matter is recycled in ecosystems
• Analyze food chains and food webs
• Understand why energy decreases at higher trophic levels
• Strengthen scientific reasoning and explanation skills

📘 Classroom-Ready & Easy to Use
This no-prep resource is perfect for fast, effective instruction. It can be used for direct teaching, independent practice, homework, review stations, or substitute plans. The structured format ensures students stay engaged while building deep conceptual understanding of ecosystem dynamics.
