Answer to Question 2
1 . Farmers or ranchers produce the raw materials that are ultimately produced into fuel, food, and fibers. They purchase inputs and services and sell to food processors. Farmers provide the management, intellect, and labor to produce the raw material.
2 . Farm input/service suppliers provide seed, fertilizers, pesticides, and equipment necessary to grow a crop. Small businesses are located in rural communities and include crop consultants; insurance agents; banks; hardware stores; and seed, fertilizer, and equipment dealerships. They may also be grain or livestock buyers at the local elevator or stockyards as well as haulers, and shippers. Examples of large businesses include companies such as John Deere and Ford-New Holland that provide tractors, tillage, planting, and harvest equipment, and seed and genetics companies such as Pioneer Hybrid International, Genetics, and Monsanto.
3 . Food and fiber processors convert raw materials or commodities such as grains and livestock produced on the farm into products that can be sold to consumers. Processing involves steps that may involve multiple businesses or a single business. Commodity processors buy raw material such as grain or livestock and do the initial conversion to food or industrial ingredients. Food or industrial product processors then take ingredients from multiple sources and create a marketable product.
4 . Marketers link the food processor to the consumer. This involves wholesale and retail sales as well as on-time delivery. Today, in contrast to much of the twentieth century, food is distributed nationally and internationally using a sophisticated system.
