GaiaOrganix is an organic food wholesale co-op linking producers and consumers. GaiaOrganix negotiates purchases by grocery and other stores from farmers who raise a variety of crops, such as fruits, vegetables, and grain. Each farmer may produce a number of crops, and each crop may be produced by a number of farmers. To provide the highest level of fresh products, the produce is shipped directly from the farm to the store. Each store may purchase from many farms, and each farm may sell to many stores. Draw an entity-relationship diagram in the third normal form showing the relationship between the producer (farms) and the retailer (stores).
