### Answer:
b. True

### Explanation:
Diffusion is indeed defined as the net movement of particles from an area where they are in higher concentration to an area where they are in lower concentration. This process occurs naturally and is governed by the second law of thermodynamics, which states that systems tend toward increased entropy or disorder. As particles move independently in a medium, such as a gas or liquid, they collide with one another and spread out over time. This movement continues until the concentration of particles is uniform throughout the area, achieving equilibrium. The concept of diffusion is fundamental in various scientific fields, including biology, chemistry, and physics, and plays a crucial role in processes such as gas exchange in respiration, nutrient absorption in cells, and the mixing of substances in solutions.
