Food Web Energy Flow is the focus of this Grade 7 Science resource for Interactions and Ecosystems, helping students trace energy through interconnected food webs and explain how producers, consumers, and decomposers depend on one another.

Rather than treating food chains as isolated sequences, students examine trophic levels, dependency chains, and interconnected food-web relationships. They explore how energy moves through an ecosystem and consider how adding or removing a species can alter trophic connections and affect network stability.

What Students Practise

• Describe energy movement from producers to consumers and decomposers.
• Identify trophic levels and dependency chains within an interconnected food web.
• Explain how changes to species presence can affect trophic connections.
• Evaluate how species changes may influence food-web network stability.

The worksheet uses multiple-choice questions, true-or-false statements, short-answer responses, a reading passage, matching, a cloze passage, an essay, and a "Did You Know?" component. This gives students opportunities to recognize relationships, apply ecological vocabulary, interpret connected systems, and communicate their reasoning in different ways.

What You Receive

• ✅ Student worksheet focused on food web energy flow and trophic links
• ✅ Student Notes & Lesson Summary supplement for reinforcing key ideas
• ✅ Separate Teacher Guide with learning objectives, teaching tips, discussion questions, and common mistakes

Classroom Use

Use this food web worksheet for Grade 7 as guided practice during an Interactions and Ecosystems lesson, independent classwork, a review activity, or a way to check students' grasp of trophic relationships. The accompanying notes can support instruction before or after the worksheet, while the Teacher Guide provides practical prompts for discussion and helps anticipate common misunderstandings.

By connecting energy flow, trophic levels, species dependencies, and ecosystem stability, the resource gives students a structured way to reason about food webs as interconnected systems rather than memorizing individual terms in isolation.
