2. What is SYMBIOSIS PARASITISM?

3. Definition of Symbiosis Parasitism
• Symbiosis parasitism is a relationship in
which one organism - the host - is the source
of food and/or shelter for another
organism, the parasite. In this
relationship, all of the benefits go to the
parasite; the host is harmed by the
relationship.

4. Example in Our Life
• An example is a human and a tapeworm living
in the intestines. The tapeworm derives food
(and shelter) from the human host; the
human is denied the nutrition that is
consumed by the tapeworm.
