Presentation transcript:

Symbiotic Relationships Created by Mr. Whittaker Woodbury School Grade 6 Science, 2005-06 Symbiotic Relationships Any close relationship between species is called symbiosis.

Mutualism Win / Win Situation + / + A symbiotic relationship in which both species benefit. How is the relationship between a bee and a flower an example of mutualism?

Commensalism Win / no affect + / 0 A symbiotic relationship in which one organism benefits and the other is not affected is called commensalism.

Parasitism Win / Lose + / - A symbiotic relationship in which one organism benefits but the other is harmed is called parasitism.

Symbiotic Relationships Quick Reference Mutualism = + / + relationship Commensalism = + / 0 relationship Parasitism = + / - relationship

Symbiotic Relationship Activity Create 2 imaginary organisms that have a symbiotic relationship. Mutualism, Commensalism, Parasitism Brainstorm organisms on a Venn Diagram & describe the type of relationship. Create a drawing showing the relationship with one sentence describing the relationship.
