The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Question**: The question asks about the implications of life without air. Air primarily consists of oxygen, which is essential for many organisms. 2. **Identifying the Role of Oxygen**: Oxygen is crucial for aerobic respiration, a process through which many organisms, including humans, generate energy. Without oxygen, aerobic respiration cannot occur. 3. **Defining Anaerobic Conditions**: When there is an absence of air (or specifically oxygen), the condition is termed anaerobic. Anaerobic conditions are characterized by the lack of oxygen. 4. **Identifying Anaerobic Organisms**: Some organisms, known as anaerobes, can survive and thrive in anaerobic conditions. These organisms do not require oxygen for their metabolic processes and can perform anaerobic respiration. 5. **Conclusion**: Life without air would be anaerobic for certain organisms. While many organisms would struggle to survive without oxygen, anaerobic organisms can adapt to such conditions. **Final Answer**: Life without air would be anaerobic. ---
