Step-by-step explanation:
Dispersal is a biological process in which a few members of a species move to a new geographical area. It can occur through various methods, such as wind dispersal, water dispersal, and dispersal by animals. The purpose of dispersal is to prevent competition among offspring and parents for resources like light or water. For example, dandelion seeds have parachutes that allow them to be carried far from their parents by the wind.
