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

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

1. Grass → It’s a plant. It makes its own food from sunlight. → Producer

2. Elephant → It eats plants. Can’t make its own food. → Consumer

3. Bacteria → Some bacteria break down dead stuff. In this context, they’re likely decomposers. → Decomposer

4. Tiger → It eats other animals (like deer). → Consumer

5. Acacia tree → It’s a tree. Makes its own food via photosynthesis. → Producer

6. Earthworm → It eats dead leaves and soil, helping break them down. Often considered a decomposer. → Decomposer

7. Mushroom → Fungi that grow on dead matter. Breaks it down. → Decomposer

8. Blackberry plant → A plant. Makes its own food. → Producer
