Question

Select two examples of spatial diffusion in the history of food systems:

A. Potato traveling from South America into other areas of the world such as Europe, India, and Africa, as a crop .
B. Tomato traveling from India outward toward China and the Middle East.
C. Wheat and barley traveling out of the Middle East and East Africa to become global crops .
D. Rice traveling from North America toward South America and Asia.

Answer 1

Two examples of spatial diffusion in food systems are the spread of the potato from South America to various parts of the world and the diffusion of wheat and barley from the Middle East and East Africa to become global crops.

Step-by-step explanation:

The question relates to spatial diffusion in the history of food systems. Two examples of this are:

• A. Potato traveling from South America to other parts of the world such as Europe, India, and Africa.
• C. Wheat and barley spreading from the Middle East and East Africa to become global crops.

The potato was first domesticated in the region of modern-day Peru and northwest Bolivia. It became a staple food crop in Europe after being introduced in the late 16th century, contributing to the population and economic growth. Similarly, wheat and barley have origins in the Fertile Crescent and spread to become staple grains in various civilizations around the world. These movements of crops are classic examples of the diffusion of agricultural products, profoundly affecting diets, economies, and cultures across the globe.
