### Step-by-Step Solution:

1. **Definition of Uricotelism**:

2. **Examples of Uricotelic Organisms**:
- Organisms that exhibit uricotelism include birds and some reptiles. They convert ammonia, a toxic byproduct of protein metabolism, into uric acid, which is less toxic and can be excreted with minimal water loss.
