2. Agriculture
is defined as the activities
concerned with the
production of plants and
animals, and related supplies,
services, mechanics, products,
processing and marketing.
• Agriculture generally has some tie-in or tie-back to animals or
plants. However, production agriculture, or farming and
ranching, accounts for only one-fifth of the total jobs in
agriculture.
– The other four-fifths of the jobs in agriculture are non farm and
non ranch jobs.
– Agribusiness refers to commercial firms that have developed with
or stemmed out of agriculture.

10. Organic Food
is a term used for foods that have been grown
without the use of chemical pesticides.
Agriscience Around Us
1. Agriscience and technologies have helped
humans change their living conditions from
dependence on hand labor to a highly mechanized
society.
• Food and Fiver production have become much more
efficient.
Agriscience Around Us
• Fewer than 2 percent of the people in America are
farmers.
– Each farmer produces enough food for approximately 135
people.
• In fact, the large surplus of food that is produced in the
United States is shipped (exported) to many other
countries in the world.
Agriscience Around Us
2. Whether you live in the
city, town, or country, you
are surrounded by the
world of agriscience.
• Plants release oxygen into
the air.
• Animals provide
companionship as pets and
assistance with work.
• Plants and Animals are
sources of food.
Agriscience Around Us
• Plants are used extensively to decorate homes,
businesses, shopping malls, buildings and grounds.
• Turf grass is used for decorative as well as soil-holding
purposes.
• Flowers used by florists.
• Lumber is shipped from the United States to other
parts of the world.
• Journalism and Communications
– Magazines, journals, and newspapers.
– Radio and Television
