Diffusion is a passive process while facilitated diffusion is an active process.

Answer

### Step-by-Step Text 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 naturally and does not require energy input from the cell, making it a passive process.

2. **Understanding Facilitated Diffusion**:
- Facilitated diffusion is a specific type of diffusion that occurs with the help of transmembrane integral proteins. These proteins assist in the movement of molecules across the cell membrane, particularly for substances that cannot easily pass through the lipid bilayer.

3. **Clarifying the Nature of Both Processes**:
- Both diffusion and facilitated diffusion are passive processes. They rely on the concentration gradient (the difference in concentration between two areas) and do not require ATP (adenosine triphosphate) or any other form of energy to occur.

4. **Conclusion**:
- The original statement claiming that facilitated diffusion is an active process is incorrect. Both diffusion and facilitated diffusion are passive processes that allow substances to move down their concentration gradient without the use of cellular energy.
