Forested land in the Amazon basin is currently being cleared for agriculture, just as land in the Midwestern U. S. was cleared for agriculture in the 19th century. The growth of plants is influenced by soil fertility, the naturally-occurring concentration of plant nutrients in the soil. Which statement below do you think best describes the relative soil fertility levels in Amazonian soils and soils in the agricultural Midwest?

a. Amazonian soils have higher fertility than Midwestern soils

b. Amazonian soils have lower fertility than Midwestern soils

c. Amazonian soils have roughly equal fertility as Midwestern soils

The correct answer is statement b.

Explanation:

This is due to the fact that the reduction of the vast majority of forest land, that is, mainly in Brazil has resulted in the extinction of the unknown and the familiar species. This has also declined the biological diversity and thus has immensely affected the fertility of the soil.

The soil has turned shallow and thus are less fertile in comparison to the Mid-Western United States. The Midwestern parts of the United States possess variety of soils, which are produced due to the glacial deposits and thus provides more fertility to the soil.
