This is the first stage in any production process. It is concerned with obtaining or extracting natural resources from the Earth? Such as minerals, fuel, raw materials or food.
Primary Industries may be further divided into two kinds.
1)-Exhaustive Industries
Those industries that take resources from nature and these resources are not replaced e.g. mining, quarrying.
2)-Non-Exhaustive Industries
Those industries that take resources that are renewed from time to time, e.g. farming, fishing.
* Primary industries are dependent on geological and climatic condition.
