Answer;
Firms --> Market For Goods and Services --> Households
Step-by-step explanation;
In product markets, business firms supply and sell goods and services while households demand and buy them. Households supply and sell factors of production, such as labor, while business firms demand and buy them.
In a market economy households provide resources and labor and purchase goods and services while firms provide goods and services and purchase resources and labor. The goal of firms in a market economy is to maximize their profits. This can best be achieved by minimizing costs in the resource market and maximizing revenues in the product market.
