In our country, vast tracts of forests are cleared and a single species of plant is cultivated. This practice promotes
(a) biodiversity in the area
(b) monoculture in the area
(c) growth of natural forest
(d) preserves the natural ecosystem in the area
(b)
The practice of clearing vast tracts of forests and cultivating a single species of plant is known as monoculture. This devastates the biodiversity in the region as the number of species lower. It likewise upsets or disturbs the natural ecosystem in the area. Hence, it decelerates the growth of the natural forest.
Hence option (b) is correct.
