Verified step by step guidance

1. Identify the key terms in the problem: 'movement along a given supply curve' and 'change in quantity supplied'.
2. Understand that a movement along the supply curve is caused by a change in the price of the good or service, not by a change in supply itself.
3. Recognize that a decrease in demand will lead to a decrease in the equilibrium price, causing a movement along the supply curve.
4. This movement along the supply curve due to a change in price is referred to as a change in 'quantity supplied', not a change in 'supply'.
5. Therefore, the correct terms to fill in the blanks are: 'demand' for the first blank and 'quantity supplied' for the second blank.
