Final answer:
The question pertains to creating supply and demand graphs for the soybean industry and an individual farmer within a perfectly competitive market. The industry graph should indicate equilibrium price and quantity, while the individual farmer's graph shows cost curves and the price as a horizontal line.
Step-by-step explanation:
The question focuses on the perfectly competitive market of the soybean industry in Canada and the cost structure of an individual soybean farmer. In a perfectly competitive market, the price is determined by the intersection of industry supply and demand, which every individual firm, such as Farmer Zeb, takes as given.
A graph representing the soybean industry would show the supply and demand curves with the equilibrium price and quantity where they intersect. Conversely, Farmer Zeb's individual graph would depict marginal cost (MC), average total cost (ATC), and average variable cost (AVC) curves with the market price represented as a horizontal line at the equilibrium price.
An important detail to include in Farmer Zeb's graph is the ATC curve, which intersects the MC at the minimum point of the ATC curve. The intersection dictates Zeb's production decisions and potential profit-maximizing quantity.
