Energy Flow in a Food Web

Energy Flow in a Food Web Worksheet (Grade 6 Science, TEKS 6.8B)

Show students that a food web is an energy system. This one-page reading and activity sheet uses a doodle food web with the sun, grass, a grasshopper, a rabbit, a frog, a fox, and a hawk. It explains that arrows show the way energy flows and that most energy at each step is transferred to the surroundings as thermal energy.

What's Inside

• A Big Question box: "How does energy move through a food web?"
• A labeled food web with arrows from the eaten to the eater
• Activity 1: Students fill in the missing energy units for a frog and a hawk on an energy pyramid
• Activity 2: Three circle-the-answer questions about arrows and thermal energy
• A visual answer key with answers marked in red

How Teachers Use It

Use it alongside an ecosystems lesson or as practice for TEKS 6.8B. The sheet takes about 10 minutes, needs no prior knowledge, and prints clearly in black and white.

This worksheet is part of the Reading in Science series for grade 6. It supports TEKS 6.8B: describe how energy is conserved through transfers and transformations in systems such as electrical circuits, food webs, amusement park rides, or photosynthesis. It is one of seven connected TEKS 6.8B sheets that follow energy through systems. The unit big idea is that energy can be stored, transferred, and transformed, but it is not created or destroyed.

Why It Works

Each sheet opens with a Big Question, teaches the key terms in plain words with simple black-and-white doodles, and then asks students to use only what the page taught. Simple whole-number energy units make conservation visible, and the visual answer key lets teachers check work fast.
