Help your students understand food chains, food webs, energy flow, trophic levels, and species interactions with this comprehensive middle school ecology worksheet bundle. These 12 resources combine direct instruction, informational readings, video worksheets, digital learning, and engaging cipher puzzles to reinforce essential ecosystem concepts in multiple ways.

In addition, your bundle includes a bonus lesson on Energy Flow in Ecosystems.

Students will trace energy through ecosystems, identify feeding relationships, analyze predator-prey interactions, and predict how human activities can affect entire food webs. The variety of formats makes it easy to introduce new concepts, provide independent practice, review before an assessment, or prepare meaningful work for a substitute teacher.

What’s Included
