If both demand and supply decrease, consumers wish to buy less andfirms wish to supply less, so output will fall. However, since consumers place a lower value on each unit, but producers are willing to supply each unit only at higher prices, the effect on price will depend on the relative size of the two changes.
Demand is from the consumer's perspective while supply is from the producer's. Supply in economics is defined as the producer's willingness and ability to supply a given good at various price points, holding all else constant. An increase in price will increase producer's revenues, thus they are willing to supply more; a decrease in price will reduce revenues, therefore producers will supply less.
