解析
Corn is an example of a commodity with seasonal production and a constant demand. Corn is produced in the fall of every year, but it is consumed throughout the year. Natural gas is an example of a commodity with constant production but seasonal demand. Natural gas is expensive to store, and demand in the United States peaks during high periods of use in the winter months. In addition the price of natural gas is different for various regions due to high international transportation costs. The demand and production of oil is more constant relative to natural gas due to the ability to transport and store oil more cheaply than natural gas. Therefore, the worldwide demand and production is relatively more constant even though it is subject to supply and demand stocks.「huixue_img/importSubject/1564169523081383936.jpeg」
