Final answer:
Farmers in modern society rely on others for machinery and resources, practice intensive agriculture, and in an agrarian society, work hard based on the seasons. The development of machines increased the efficiency of farming.
Step-by-step explanation:
Farmers in modern society rely on various individuals involved in the design and manufacture of machinery, the production of fertilizers, and transportation. They practice intensive agriculture, focusing on a small number of crops to generate surplus for trade and meet household needs.
In an agrarian society, farmers worked hard and relied on the seasons to dictate their activities, tilling the soil and planting crops. The development of machines in agriculture increased efficiency and allowed for larger quantities and consistent quality of crops.
