Which one of the following pairs mismatched -

Options

A. Savanna- acacia trees
B. Coniferous forest - evergreen trees
C. Tundra-permafrost
D. Prairies-epiphytes

Answer

To determine which pair is mismatched, we need to analyze each option provided in the question.

### Step-by-Step Solution:

1. **Identify the Ecosystem and its Characteristics**:
- Understand the characteristics of each ecosystem mentioned in the options. For example, savannahs are known for having scattered trees (like acacia), grasslands have more herbs and shrubs, coniferous forests are characterized by evergreen trees, and tundra ecosystems are associated with permafrost.

2. **Evaluate the Pairs**:
- **Acacia Trees and Savannah**: Acacia trees are indeed found in savannah ecosystems, where they coexist with grasses. This pair is correctly matched.
- **Coniferous Forests and Evergreen Trees**: Coniferous forests are known for their evergreen trees, which do not lose their leaves in autumn. This pair is also correctly matched.
- **Tundra and Permafrost**: The tundra ecosystem is characterized by permafrost, where the ground remains frozen for most of the year. This pair is correctly matched as well.
- **Prairies and Epiphytes**: Prairies are grassland ecosystems with few trees, and epiphytes are plants that grow on other plants, typically found in forested areas. Since prairies lack the large trees that epiphytes need to grow on, this pair is mismatched.

3. **Conclusion**:
- The mismatched pair is **Prairies and Epiphytes**.

### Final Answer:
The mismatched pair is **Prairies and Epiphytes**.
