Clearing forests and grasslands for farming reduces because land is used to grow only a few crops.

a. ecosystems
b. biodiversity
c. biomass
d. carrying capacity

B. biodiversity

Explanation:

The forests and the grasslands are the reserves of biodiversity of flora and fauna. The clearing of the forests and grassland will remove the vegetation from the area which will lead to the reduction of the fauna species from the area because of the loss of habitat. Although the agriculture will facilitate the growth of few crops but this may not be able to compensate the loss of large biodiversity.  

mountains can affect the climate of nearby lands. in some areas, mountains block rain, so that one side of a mountain range may be rainy and the other side may be a desert. much of airborne moisture falls as rain on the windward side of mountains.
