In this fun new puzzle we feature of bunch of corn ears drying in the warm summer sun. If you didn't know, an ear is the grain-bearing tip part of the stem of a cereal plant, such as wheat or corn. Maize is widely cultivated throughout the world, and a greater weight of maize is produced each year than any other grain. Sugar-rich varieties called sweet corn are usually grown for human consumption as kernels, while field corn varieties are used for animal feed, various corn-based human food uses (including grinding into cornmeal or masa, pressing into corn oil, and fermentation and distillation into alcoholic beverages like bourbon whiskey). Corn is also used in making ethanol and other biofuels. Most historians believe maize was domesticated in the Tehuacan Valley of Mexico. After the arrival of Europeans in 1492, Spanish settlers consumed maize and explorers and traders carried it back to Europe and introduced it to other countries. Maize spread to the rest of the world because of its ability to grow in diverse climates.
