This is because Corn is grown on land and has important values to man .These values include as a source of food for man and animals. It is also used as raw materials for the production of certain goods such as flour etc.

It is an energy resource because fermentation of corn gives rise to ethanol fuel which is used as a source of power to run machines and other equipment.
