This worksheet helps students classify living things into producers, consumers, and decomposers.

Let’s go through each living thing one by one and decide if it is a producer, consumer, or decomposer.

Remember:
- Producers make their own energy (like plants using sunlight).
- Consumers eat other living things to get energy.
- Decomposers break down dead stuff (dead plants, animals) to get energy.

---

1. Grass → It’s a plant. Plants use sunlight to make food.
→ Producer

2. Elephant → Eats plants (grass, leaves). Doesn’t make its own food.
→ Consumer

3. Bacteria → Some bacteria break down dead things. In this context, we’re talking about decomposer bacteria.
→ Decomposer

4. Tiger → Eats other animals (like deer or zebra).
→ Consumer

5. Acacia tree → It’s a tree — makes its own food from sunlight.
→ Producer

6. Earthworm → Eats dead leaves and soil matter — breaks them down.
→ Decomposer

7. Mushroom → Fungi that grow on dead wood or soil — they decompose organic material.
→ Decomposer

8. Blackberry plant → A plant with berries — uses sunlight to make food.
→ Producer

9. Grizzly bear → Eats fish, berries, sometimes meat — gets energy by eating others.
→ Consumer

10. Rattle snake → Eats small animals like mice or birds.
→ Consumer
