What is the difference between a cash crop and subsistence farming?

A cash crop is a crop grown primarily for sale and profit in the market, such as cotton or tobacco, while subsistence farming focuses on producing enough food to meet the needs of the farmer and their family, with little surplus for sale. Cash crops are typically grown in larger quantities and often rely on commercial farming practices, whereas subsistence farming is more about self-sufficiency and may involve diverse crops. The economic goals and farming practices differ significantly between the two.
