We know, the famous grassland of the world 'pampas' is located in Argentina This grassland is the grazing land for the thousands of livestock. So, animal husbandry is very popular here. The reared animals are used for milk, meat, wool, etc. So, as Argentina is famous for animal husbandry, it is exporting large quantity of meat.

We know, the land structure of any basin is very fertile. There is alluvial soil in the basin of Amazon which very fertile. Also, the rainfall usually occurs frequently, as the water cycle is frequent there. So, due to the presence of fertile soil and water resources, Amazon basin is covered by dense forest.

The western mountains of south America is sparsely populated because of its difficult topography for the conduction of different economic, physical and other activities like agriculture, transport, and other physical facilities.
    In the other hand, the costal area of south America is densely populated because of the availability of the different physical facilities, establishment of different industries, sea route to any part...

About 80% of total population of Brazil lives in city area because:

...

Any two push factors of this type of migration are:

Andes region is likely to be compared as the mountain region of Nepal and the llamas with sheep. We know, the topography mountain range is difficult. So, the development of any infrastructure is harder. Any people use sheep as a transporting means in such difficult topography. Similarly, llamas in Andes region is used as transporting means in the mountains of Andes region as other transporting means are absent there.
