Why are profits not guaranteed for firms supplying nonrenewable resources?Multiple select question.There is a low likelihood of these resources being purchased.Extraction can be very expensive.The price they will receive in markets is uncertain.Technology has virtually eliminated the need for these resources.

Profits are not guaranteed for firms supplying nonrenewable resources due to several reasons:

1. Extraction can be very expensive: Nonrenewable resources, such as oil, coal, and natural gas, are often located deep within the earth. Extracting these resources requires significant investment in equipment, labor, and technology. If the costs of extraction are higher than the price the firm can sell the resources for, the firm will not make a profit.

2. The price they will receive in markets is uncertain: The prices of nonrenewable resources can fluctuate greatly due to changes in supply and demand. For example, if a new, large deposit of oil is discovered, the increased supply could lower the price of oil. Similarly, if demand for oil decreases due to a shift towards renewable energy, the price of oil could also decrease. These price fluctuations make it difficult for firms to predict their profits.

3. Technology has virtually eliminated the need for these resources: Advances in technology have led to increased efficiency and the development of renewable energy sources. This reduces the demand for nonrenewable resources, which can lower the price firms receive for these resources and thus their profits.

The option "There is a low likelihood of these resources being purchased" is not necessarily true. Nonrenewable resources are still widely used in many industries, so there is a high likelihood of these resources being purchased. However, the demand for these resources can change, which can affect the price and thus the profits of firms supplying these resources.
