Grade 4 Ecosystems and Food Chains word search, scramble and crossword puzzle

I made this ecosystems and food chains puzzle set for my 4th graders during our life science unit. The kids could name a few animals and plants but had no idea what words like producer, consumer, or decomposer meant when we started learning about how energy moves through an ecosystem. They also kept mixing up the levels in a food chain and forgetting which direction the arrows should point . So I put together a word search, a word scramble, and a crossword using words like ecosystem, producer, consumer, decomposer, herbivore, carnivore, omnivore, predator, prey, food chain, food web, and energy . I also included a few like "sun" and "plant" because they're the foundation of every food chain . Nothing fancy — just puzzles to help the vocabulary finally stick.

The PDF is four pages. Three puzzles plus one answer key page. The word search works well for quiet time after recess or independent practice. The scramble gets them talking because they argue about the spelling of "decomposer" or whether a bear is a carnivore or omnivore (it's an omnivore—they always have opinions about it) . The crossword I use for partners or as a review, and I usually have a food web diagram nearby for the kids who need the visual support to see the connections between organisms . I added a couple simple sun, plant, rabbit, and wolf drawings but nothing too busy.

Works for 4th through 5th grade. Print and go. Sometimes I have early finishers draw a simple food chain and label the producer, consumer, and decomposer on the back. The kids actually ask for these now.
