Which one of the following biome experiences minimu m average an nual rain fa ll and minimum average annual temperature :-

Options

A. Desert
B. Arctic and alpine tundra
C. Coniferous forest
D. Temperate forest

Answer

To determine which biome experiences the minimum average annual rainfall and minimum average annual temperature, we will analyze the options provided.

### Step-by-Step Solution:

1. **Identify the Biomes**: The question requires us to evaluate different biomes based on their average annual rainfall and temperature. The biomes mentioned include desert, arctic and alpine tundra, conifer forest, and temperate forest.

2. **Analyze Desert Biome**:
- Average Annual Rainfall: Approximately 50 mm
- Average Annual Temperature: Approximately 20°C
- Conclusion: While the desert has low rainfall, its temperature is relatively high.

3. **Analyze Arctic and Alpine Tundra**:
- Average Annual Rainfall: Approximately 50 mm
- Average Annual Temperature: Approximately -10°C
- Conclusion: This biome has low rainfall and the lowest temperature among the options.

4. **Analyze Conifer Forest**:
- Average Annual Rainfall: Approximately 250 mm
- Average Annual Temperature: Approximately 0°C
- Conclusion: This biome has higher rainfall and a higher temperature compared to the previous two.

5. **Analyze Temperate Forest**:
- Average Annual Rainfall: Approximately 200 mm
- Average Annual Temperature: Approximately 10°C
- Conclusion: This biome also has higher rainfall and temperature than the desert and tundra.

6. **Compare the Results**:
- The desert has low rainfall but higher temperature.
- The arctic and alpine tundra has both low rainfall and the lowest temperature.
- The conifer forest and temperate forest have significantly higher rainfall and temperatures.

7. **Final Conclusion**: The biome that experiences both minimum average annual rainfall and minimum average annual temperature is the **Arctic and Alpine Tundra**.

### Answer:
**The correct answer is: Arctic and Alpine Tundra.**
