What is the difference between a good that is a need and a good that is a want Provide one example of each.?

A good that is a need is essential for survival and basic functioning, such as food or clean water, while a good that is a want is not essential and is driven by personal desire or preference, like a luxury car or designer clothing. For example, bread represents a need because it provides sustenance, whereas a smartphone is a want, as it enhances communication and entertainment but is not vital for survival.
