Arctic tundra is

Options

A. Highest latitudinal biome
B. Located in rain shadow
C. Characterized by Capparis and Prosopis species
D. Highest altitudinal biome

Answer

**Step-by-Step Solution:**

1. **Understanding the Arctic Tundra**: The Arctic tundra is a biome characterized by its cold climate, short growing seasons, and specific vegetation types. It is primarily found in regions close to the North Pole.

2. **Identifying the Options**: The question provides four options regarding the characteristics of the Arctic tundra:
- (A) The highest latitudinal biome
- (B) Located in rain shadow
- (C) Characterized by capparis and prosopis species
- (D) The highest altitudinal biome

3. **Evaluating Each Option**:
- **Option A**: The Arctic tundra is indeed the highest latitudinal biome as it is located at high latitudes, specifically above the Arctic Circle.
- **Option B**: The Arctic tundra is not located in a rain shadow. Rain shadows are typically found in mountainous areas where one side receives high rainfall and the other side is dry.
- **Option C**: Capparis and Prosopis species are not characteristic of the tundra; they are found in different ecosystems, such as thorn forests.
- **Option D**: While the tundra can be at high elevations, it is primarily defined by its latitude rather than altitude.

4. **Conclusion**: Based on the evaluation, the correct answer is **Option A**: The Arctic tundra is the highest latitudinal biome.
