Ultimate Consumers are the final consumers in the chain of a resource life. An example would be potash mined as fertilizer – it is first mined by a mining company, then sold to fertilizer companies, then sold to farmers, who use it on their crops, who sell their crops to grocery store chains, who finally sells the finished vegetable to individuals and families, who eat it. The person who ate the vegetable would be the Ultimate Consumer of the original potash.
