Diffusion is a slow process and is not dependent on a living system.

Answer

**Step-by-Step Solution:**

1. **Understanding Diffusion**:
- Diffusion is the movement of molecules from an area of higher concentration to an area of lower concentration. This process occurs until equilibrium is reached.

2. **Nature of Diffusion**:
- Diffusion is a passive process, meaning it does not require energy input from the system. It relies solely on the concentration gradient of the substances involved.

3. **Dependence on Living Systems**:
- The statement claims that diffusion is not dependent on a living system. This is accurate because diffusion can occur in both living (e.g., across cell membranes) and non-living systems (e.g., gases in the air).

4. **Rate of Diffusion**:
- While diffusion can be a slow process, the rate can vary depending on factors such as temperature, concentration gradient, and the nature of the substances involved. However, it is generally slower compared to other transport mechanisms like active transport.

5. **Conclusion**:
- Based on the understanding of diffusion, the statement "Diffusion is a slow process and is not dependent on a living system" is true.

**Final Answer**: The statement is true.
