Frisbees represent abiotic components. These are things that plants take from the soil, water and air to make food. The number of objects should equal the number of producers. Place the frisbees in boxes within the playing area. Producers are the only players who can take frisbees from the boxes.
Consumers get frisbees by making a two-handed tag on a producer holding a frisbee.
The goal of consumers is to get as many frisbees as possible from producers and keep them. 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.
