How does agriculture, an activity primarily in the primary sector, spill over into the secondary and tertiary sectors?

The US energy output has increased significantly since 2012. What is one of the key factors contributing to this increase?

One of the key factors contributing to the increase in U.S. energy production since 2012 is the introduction of novel extraction techniques such as hydraulic fracturing (fracking).

What factor(s) explains the relative decline of the primary sector in the U.S.?

Primarily it has been due to technological improvements and the rise in agricultural productivity, which has allowed the products of the primary sector to be obtained with fewer workers

What are the four categories of the tertiary sector in the alternative categorization developed by the authors of the textbook? What kinds of activities are included in each?

The four categories are: ownership transactions (e.g. homeownership and activities involved in ownership transfers such as: transportation, warehousing, wholesale and retail trade, and real-estate rental and leasing), information and management (information, finance and insurance, and professional, scientific, and technical services, administration, waste management and management of companies.), private social services (education, health care, and social services), and entertainment (which includes arts, entertainment, recreation, accommodation and food services)

Briefly define the primary, secondary, and tertiary sectors.

The primary sector involves the extraction and simple processing of raw materials which are sold as inputs into the production process. The secondary sector transforms these inputs into final products to consumers. The tertiary sector involves the provision of services, rather than tangible goods
