Name the ecological adaptations shown by desert plants (xerophytes).

Explanation

### Step-by-Step Solution

1. **Understanding Ecological Adaptations**:
- Ecological adaptations refer to the changes that plants undergo to survive in their specific environments. In the case of desert plants, these adaptations help them cope with harsh conditions such as extreme temperatures and limited water availability.

2. **Long Roots**:
- Desert plants have long roots that extend deep into the ground. This adaptation allows them to reach water that is not accessible to plants with shorter roots. The long roots help them survive during dry periods when surface water is scarce.
