Q.Distinguish between individual supply and market supply.

Supply, like demand, can be looked at from the point of view of one seller or the whole market.

Individual supply is the quantity of a commodity that a single producer or firm is willing and able to offer for sale at a given price, over a given period. Market supply is obtained by adding together (horizontally, at each price) the individual supplies of every producer selling that commodity in the market. For example, if three farmers are willing to supply 10, 15 and 20 units respectively at a price of ₹8 per unit, the market supply at ₹8 is $10+15+20=45$ units. Market supply, not any one seller's individual supply, is what interacts with market demand to determine the equilibrium price.

Treating 'market supply' as simply a larger single producer's supply rather than correctly understanding it as the SUM across many independent sellers, each responding to the same market price.
