The population in country C decreases, due to a lower birth rate. At the same time, there is an increase in the cost of fertilizer, which is used to grow vegetables. Explain how the market for vegetables will be affected by these changes. Clearly indicate how the equilibrium price and equilibrium quantity will be affected by these changes. Make use of a combination of diagrams and verbal explanation to explain your answer. Note that your diagrams should be properly annotated and that marks will be deducted for any missing labels on your diagram.
