Q. With reference to Grasslands, which of the following statements are correct?
1.They are characterized by sandy soils with no vegetation.
2.They are distributed mainly in semiarid and arid area.
3.They play a crucial role in carbon storage and nutrient cycling.
4.They are crucial habitats for Bengal florican.
Select the correct answer using the codes given below:
Explanation –
Statement 1 is incorrect. Grasslands are characterized by vast open areas dominated by grasses and have very few trees. They are ecosystems with significant vegetation, primarily grasses, and are not barren or devoid of vegetation.
Statements 2, 3 and 4 are correct. Grasslands are often found in regions with limited rainfall, which prevents the growth of forests and supports grass dominance. They are typically located in areas that are not dry enough to become deserts but not wet enough to support forests. Grasslands are important for carbon storage and nutrient cycling. They contribute to biogeochemical cycles and help regulate climate by storing carbon in their soils. The Bengal florican is a bird species that inhabits grassland habitats, making these ecosystems crucial for its survival. The Kachchh district in Gujarat, India, is home to one of the country’s largest grassland areas, known as Banni.
