The diagram illustrates the stages in the food production chain of the United States.
Overall, it is a linear process, and the whole process contains four main stages, which start with the Production of food and end with the Home and Restaurant Consumer consuming this food.
At the beginning of the process, crows produce milk, which is collected and sent to the processing factory. The factory worker follows the role and regulation, completes their work, and shifts to the next stage, where food is distributed, well-preserved, and ready for delivery nearest Restaurant and Retail.
For the remaining process, after completing the delivery process, in the next step, the Restaurant chef and the housewife start their preparation in different ways. They used it like an ingredient and used it in different meals. At last, after completing the Restaurant Preparation, it is now serving and presented in front of the Restaurant customers and Home Consumers.
