The major purpose of this activity is for students to become familiar with the concept of symbiosis as one example of interdependence in ecological systems. There are other pairs which may be used. You will not use all of these. Some students may research more than one organism. What would happen if one of them wasn't there.
Students can report their research to the class.
To play the card game, the class should be divided into groups of five or six students. Shuffle and deal out all cards. Play starts to the left of the dealer and rotates in a clockwise manner. Each player draws one card from the player to his or her left. After the player has drawn a card, that player may lay down all cards in his or her hand which form symbiotic pairs.
