Decomposers can get frisbees only by making a two-handed tag on a consumer holding a frisbee. When decomposers get an object, they return it to the box. Individual players can hold only one frisbee at a time. When players are tagged, they must give up the frisbee they are holding. Players can toss and pass frisbees to other members of their own group before they get tagged.
Producers begin the game by running to collect objects.
Consumers are allowed into the playing area a few moments after producers. Decomposers enter the area last. Tell students that humans are consumers but that they have the ability to consume much more than other animals. When you play the game this time, the consumers can take two frisbees at a time, rather than only one as in the first part of the game. Tell students that because of people's impact on nature, often part of the ecosystem and the animals in it are removed.
