Answer/Explanation:
Stationary organisms generally do not move by self locomotion.They could move through the actions of external forces such as moving water but cannot move alone.
Most stationary organisms (also called sessile organisms) have a motile phase in their life cycle. This allows them do disperse across longer distances. This is important for the survival of the species, as it means they can exploit a larger food supply and other resources.
