Summarize this article for a 10 year old
A supply chain, sometimes expressed as a "supply-chain",[1] is a complex logistics system that consists of facilities that convert raw materials into finished products and distribute them[2] to end consumers[3] or end customers.[4] Meanwhile, supply chain management deals with the flow of goods within the supply chain in the most efficient manner.[5]
In sophisticated supply chain systems, used products may re-enter the supply chain at any point where residual value is recyclable. Supply chains link value chains.[6] Suppliers in a supply chain are often ranked by "tier", with first-tier suppliers supplying directly to the client, second-tier suppliers supplying to the first tier, and so on.[7]
The phrase "supply chain" may have been first published in a 1905 article in The Independent which briefly mentions the difficulty of "keeping a supply chain with India unbroken" during the British expedition to Tibet.[8]
