Select a pair which contains one producer and one decomposer respectively.

Options

A. Deer, wheat plant
B. Sugarcane, rabbit
C. Wheat plant, mushroom
D. Fungi, frog

Explanation

To answer the question "Select a pair which contains one producer and one decomposer respectively," we need to understand the definitions of producers and decomposers.

### Step-by-Step Solution:

1. **Understand Producers**:
- Producers are organisms that can make their own food through processes like photosynthesis. They are also known as autotrophs. The most common examples of producers are plants.

2. **Understand Decomposers**:
- Decomposers are organisms that break down dead organic material and waste. They help recycle nutrients back into the ecosystem. Decomposers include bacteria and fungi.

3. **Analyze the Options**:
- **Option 1**: Deer (Consumer) and Wheat Plant (Producer) - This option has a producer (wheat plant) but does not have a decomposer.
- **Option 2**: Sugarcane (Producer) and Rabbit (Consumer) - This option has a producer (sugarcane) but does not have a decomposer.
- **Option 3**: Wheat Plant (Producer) and Mushroom (Decomposer) - This option has one producer (wheat plant) and one decomposer (mushroom).
- **Option 4**: Fungi (Decomposer) and Fog (Not a relevant organism) - This option has a decomposer (fungi) but does not have a producer.

4. **Identify the Correct Pair**:
- The only option that contains one producer and one decomposer is **Option 3**, which is the Wheat Plant (Producer) and Mushroom (Decomposer).

### Final Answer:
The correct pair that contains one producer and one decomposer is **Wheat Plant and Mushroom**.
