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. When a player does not have any cards left in his or her hand the game is over. The player with the largest number of pairs at the end of the game is the winner. Two unlike organisms living together.
