Osmosis, diffusion and facilitated diffusion are all examples of 1. Active transport
2. Passive transport
3. Photosynthesis
3. Asexual reproduction

2. Passive Transport

Explanation:

In passive transport, molecules are going down their concentration gradient with no energy involved. In osmosis, water molecules move from a higher to lower concentration. In facilitated diffusion, molecules go from higher to a lower concentration through a transport protein.
