 Each group will be given a stack of cards with organisms that interact with each other  Your Task:  Pair the organism that interact with each other  Group the Pairs together based on similar relationships:  +/++/0+/-  Have me check your work!

A close, prolonged relationship between two or more different organisms of different species where at least one organism benefits PAGE 8 of your packets!

 Parasitism  Commensalism  Mutualism

 One organism benefits and another is unaffected  +/0  Example: Hermit Crabs using shells from other organisms  Its like: A race car drafting

 both organisms involved benefit from the relationship  +/+  Example: NEMO! Marlin lives in an anemone which provides protection for him, and he eats the algae and excretes waste that the Anemone can use  Its like: Working together as a team!

 One organism benefits at the expense of the other (one suffers)  +/-  Example: Leeches attach to other animals to suck out blood to feed on  Its Like: A thief and their victim

 On a piece of paper to be handed in before you leave write what type of symbiotic relationship is being described:  The remora is a fish that in this picture is attached to a sea turtle. It gets a free ride from the turtle and feeds on the scraps of food it leaves behind

Symbiosis Commensalism Mutualism Parasitism Organisms interact in other ways besides eating each other. These symbiotic relationships play an important role in ecosystems. +/+ +/0+/- Clown Fish and Anemones Working together on a project A drafting car A thief and a victim Hermit Crabs and other organisms Shells Leech and host a close relationship between two organisms of different species that benefits atleast one of them
