Producer Consumer Decomposer Worksheet - Free Printable

Let’s look at the chart. It shows three groups: Producers, Consumers, and Decomposers.

We need to check if everything is sorted correctly into these groups.

First, let’s remember what each group means:

- Producers make their own food (usually plants using sunlight).
- Consumers eat other living things for energy (animals, including humans).
- Decomposers break down dead stuff and recycle nutrients (like fungi and bacteria).

Now let’s go group by group.

---

Producers:
- Trees (the icon with two trees) → yes, producers.
- Grass → yes.
- Christmas tree → it’s a plant, so yes.
- Flower → yes.
- Maple tree → yes.
- Strawberry → it’s a fruit from a plant, but the *plant* is the producer — still okay to include as part of the producer category.
- Grapes → same as strawberry — comes from a vine, which is a producer.

✔ All items under “Producers” are correct.

---

Consumers:
- Cow → eats grass → consumer ✔
- Boy → eats food → consumer ✔
- Dog → eats meat or dog food → consumer ✔
- Elephant → eats plants → consumer ✔
- Mom → human → consumer ✔
- Teacher → human → consumer ✔
- Rabbit → eats plants → consumer ✔

✔ All items under “Consumers” are correct.

---

Decomposers:
- Mushrooms (top icon) → decomposer ✔
- Bacteria → some types are decomposers ✔
- Mushroom (again) → decomposer ✔
- Worm → breaks down dead matter → decomposer ✔
- Fungi → decomposers ✔
- Snail → wait… snails usually eat live plants or algae — they’re more like consumers! ✘
- Bacteria (again) → decomposer ✔

Uh oh — snail is probably not a decomposer. Most snails are herbivores or omnivores that eat living material, not decaying matter. So it should be in “Consumers,” not “Decomposers.”

Also, note: “bacteria” appears twice — once with little germ icons, once with a single cell drawing. That’s fine — different kinds of bacteria can be decomposers.

But the snail is misplaced.

So the only error is: snail is in the wrong group.

Final Answer: The snail should be moved from Decomposers to Consumers.
