Looking for a fun, no-prep way to review food chains, food webs, and ecosystem vocabulary? This Food Chain and Food Web Vocabulary Cipher Puzzle gives students an engaging way to practice important ecology terms while decoding a hidden message.

Students read each clue, identify the correct vocabulary term, use the cipher key to find the matching number, and convert each number to a letter. Once all 20 questions are complete, students write the letters in order and add spaces to reveal the hidden message.

Please have a look at the preview to see how it works.
