Xeric environment is characterised by

Options

A. Precipitation
B. Low atmospheric humidity
C. Extreme of temperature
D. Extreme of temperature

Explanation

To answer the question "Xeric environment is characterised by", we can follow these steps:

### Step-by-Step Solution:

1. **Define Xeric Environment**:
- A xeric environment refers to a type of ecosystem that is characterized by very low moisture levels. This is often associated with arid or semi-arid regions.

2. **Identify Key Characteristics**:
- The primary characteristic of a xeric environment is low atmospheric humidity. This means that the air in such environments contains very little moisture.

3. **Consider Other Factors**:
- While temperature can vary in xeric environments, it is not a defining characteristic. The temperature can be extreme, but this is dependent on other factors such as altitude and latitude.

4. **Conclusion**:
- Therefore, the most accurate characteristic of a xeric environment is low atmospheric humidity.

### Final Answer:
Xeric environment is characterised by low atmospheric humidity.
