Final answer:
The question refers to crops like sugar, cotton, coffee, and corn, which are grown for their commercial value and often constitute a primary commodity for regions or countries.
Step-by-step explanation:
The crop described in the question is one produced for its commercial value, which is often a primary commodity for a country or region. These crops are typically grown for sale and include examples like sugar, cotton, and coffee. Corn is another example of a major agricultural crop that is included in this category. It is widely used to create products for different industries and is commonly modified through plant biotechnology. Corn is produced in most countries around the world and ranks as the third-most planted field crop after wheat and rice. Depending on market conditions, farmers may choose to grow different crops that are commercially viable or offer better returns, as the competition and prices influence their decision-making.
Crops can be categorized based on their use and the degree of processing they undergo. They can range from food crops that are not commercially processed to those that are, as well as focusing on other uses such as fibre, seed production, and more specialized forms of agriculture including hydroponic culture, aquaculture, and viticulture.
