Which of the following pairs is mismatched?

Options

A. Tundra - Permafrost
B. Taiga Cone-shaped canopy
C. Tropical evergreen forest - Broad-leaved trees
D. Tropical savanna - Needle-leaved trees

Answer

To determine which pair is mismatched, we will analyze each provided pair of ecosystems and their characteristics.

1. **Tundra and Permafrost**:
- Tundra is a cold biome characterized by low temperatures and a short growing season.
- Permafrost refers to permanently frozen ground, which is a common feature in tundra regions.
- **Conclusion**: This pair is correctly matched.

2. **Taiga and Coniferous Forests**:
- Taiga, also known as boreal forest, is characterized by coniferous trees such as pines, spruces, and firs.
- These trees are adapted to cold climates and have needle-like leaves, which help in reducing water loss.
- **Conclusion**: This pair is correctly matched.

3. **Tropical Evergreen Forest and Broadleaf Trees**:
- Tropical evergreen forests are known for their dense vegetation and broadleaf trees, which thrive in warm, humid conditions.
- These forests have a rich diversity of species due to the favorable climate.
- **Conclusion**: This pair is correctly matched.

4. **Tropical Savanna and Needle-like Trees**:
- Tropical savannas are characterized by grasslands with scattered trees.
- The trees in savannas are typically not needle-like; instead, they have broad leaves or are drought-resistant species.
- **Conclusion**: This pair is mismatched.

**Final Answer**: The mismatched pair is **Tropical Savanna and Needle-like Trees**.
