What advantage over an aquatic organism does a terrestrial organism have with regard to obtaining oxygen for respiration?

Explanation

**Step-by-Step Solution:**

1. **Understanding the Environment**:
- Aquatic organisms live in water, while terrestrial organisms live on land. This fundamental difference in habitat affects how they obtain oxygen for respiration.

2. **Oxygen Availability**:
