Desert biome does not support much vegetation as it lacks

Options

A. Sufficient light
B. Favourable temperature
C. Sufficient water
D. Sufficient nutrients

Explanation

**Step-by-Step Solution:**

1. **Understanding the Desert Biome**: The desert biome is characterized by extreme conditions, primarily high temperatures and low precipitation. This environment significantly affects the types of vegetation that can thrive there.

2. **Temperature**: Deserts typically experience high temperatures during the day, which can lead to rapid evaporation of moisture. This high temperature contributes to the overall dryness of the environment.

3. **Water Scarcity**: One of the most critical factors limiting vegetation in the desert biome is the lack of water. Deserts receive very little rainfall, which is essential for plant growth. The scarcity of water means that plants cannot survive or flourish.

4. **Precipitation Levels**: Deserts are defined by their low levels of precipitation, often receiving less than 250 mm (10 inches) of rain per year. This lack of moisture is a primary reason why vegetation is sparse.

5. **Conclusion**: Due to the combination of high temperatures and insufficient water availability, the desert biome does not support much vegetation. Therefore, the correct answer to the question is that the desert biome lacks sufficient water.

**Final Answer**: The desert biome does not support much vegetation as it lacks sufficient water.
