1. Economics is the study of how people choose to use resources.
Resources include the time and talent people have available, the land, buildings, equipment, and other tools on hand, and the knowledge of how to combine them to create useful products and services.
2. Needs are limited. These include food, liquid, heat, shelter, clothing (material needs), self-esteem and being loved (psychological and emotional needs).
Whereas Wants are unlimited. Be it a farmer in Africa, a manager in the UK or the richest individual in the world. There is always something which he or she wants more of.

3. Land is the economic resource encompassing natural resources found within an economy. This resource includes timber, land, fisheries, farms and other similar natural resources. Land is usually a limited resource for many economies. Although some natural resources, such as timber, food and animals, are renewable, the physical land is usually a fixed resource. Nations must carefully use their land resource by creating a mix of natural and industrial uses.
Labor represents the human capital available to transform raw or national resources into consumer goods. Human capital includes all able-bodied individuals capable of working in the economy and providing various services to other individuals or businesses. This factor of production is a flexible resource as workers can be allocated to different areas of the economy for producing consumer goods or services. Human capital can also be improved through training or educating workers to complete technical functions or business tasks when working with other economic resources.
Capital has two economic definitions as a factor of production. Capital can represent the monetary resources companies use to purchase natural resources, land and other capital goods. Monetary resources flow through a nation’s economy as individuals buy and sell resources to individuals and businesses.
Capital also represents the major physical assets individuals and companies use when producing goods or services. These assets include buildings, production facilities, equipment, vehicles and other similar items. Individuals may create their own capital production resources, purchase them from another individual or business or lease them for a specific amount of time from individuals or other businesses.
Entrepreneurship is considered a factor of production because economic resources can exist in an economy and not be transformed into consumer goods. Entrepreneurs usually have an idea for creating a valuable good or service and assume the risk involved with transforming economic resources into consumer products. Entrepreneurship is also considered a factor of production since someone must complete the managerial functions of gathering, allocating and distributing economic resources or consumer products to individuals and other businesses in the economy.
