Ecosystems & Food Webs

Inside the case file

Track the balance of nature. This printable Ecosystems & Food Webs Reading Mystery turns a nonfiction passage about how living things depend on each other into a reading-detective investigation for Grades 3–6 classroom teachers, homeschoolers, and tutors. It drops straight into a life science, ecosystems, or habitats unit and turns comprehension practice into a case they want to crack.

Students read for clues, use text evidence to eliminate suspects, and close the case one answer at a time. No apps, no fuss, no prep.

The Case

The balance of an ecosystem has been thrown off, and a line-up of suspects is waiting. The only way to crack the case is to read closely about ecosystems and food webs — producers, consumers, decomposers, and how energy flows through a habitat — using every comprehension answer as a clue to rule a suspect out, until just one remains.

How the Reading Mystery Works

Students step into the role of Reading Detectives, reading about ecosystems and food webs and knocking a suspect off the list with every text-based answer until the case is solved.
