Just a term used for when a species uses another for survival, but the other does not.
Example:
Parasitic Symbiosis =
Slime girl gets food, shelter, and protection from human. In human’s case, it’s not really the same thing if he/she does it for companionship and not a case for survival.
Human has a higher chance to die in this kind of relationship. Slime will move on if human dies and find someone else.
Symbiotic Relationship =
Slime girl gets food, shelter. Protects human from harm because human is a source of food.
