Describe the characteristics of the sahel.

It is a transitional ecoregion of semi-arid grasslands, savannas, steppes, and thorn shrublands lying between the wooded Sudanian Savanna to the south and the Sahara to the north. The topography of the Sahel is mainly flat; most of the region lies between 200 and 400 meters (660 and 1,310 ft) in elevation.

I'm not sure what kind of answer your looking for but here's a response:

The Sahel region is a dry grassland area that stretches from the Atlantic Ocean to the Red Sea. This area is a transition zone between the Sahara Desert in the north and the tropical savannas to the south. It is more heavily populated than the Sahara, and rainfall varies greatly from year to year. Some years, it never rains. This is known as a drought or dry period.

answer; i do believe its (b) 12.5 years of age;

every society, in order to meet the needs of it's people, has to answer three basic questions:

- what should we produce?

- how should we produce it?

- for whom should we produce it?

this questions must be answered in order to, option b, aid in production decisions.

every country can't produce everything, no matter how rich their land is. it may be a matter of technology, resources or geographical conditions. so, these three questions must be resolved in order to get the most of the production of each land.

hope this !
