Supply: supply reffers to the quantities of commodity that a seller is willing and able to sell at its different prices at a point of time.In other words supply reffers to a schedule showing various quantities of a commodity that the producers are willing and able to sell at different prices of the commodity at a point of time.

         According to law of demand other things remaining unchanged as the price of commodity rises its supply increases and if the price of commodity falls its supply decreases.

Supply curve:  supply curve is a graphic presentation of supply schedule indicating the positive relationship between price and quantity supplied.the supply curve slopes upwards which means when price of the commodity rises its supply increases.The supply curve has two aspects viz individual supply curve and Market supply curve both sloping upwards.Individual supply curve is a supply curve of an individual firm in the market and market supply curve is a graphic representation of market supply schedulr ie, all firms in the market simply called industry.thus industry consists of all firms in the market and its supply makes Market supply.

it can be seen from the figure the(both individual and market supply curve) price of the commodity is rising and its supply is increasing which causes supply curve to slope upwards
