Real-Life Application Based Questions

(ii) Why do many grassland animals like bison and antelope run fast?
Ans: Since grasslands are open with little tree cover, there is no place to hide from predators, so speed is a survival adaptation.

(iii) Why are grasslands in some regions shrinking over time?
Ans: Human activities like farming, urbanization, and overgrazing are reducing natural grassland areas, leading to habitat loss for many species.

(iv) Why is cattle ranching common in the Pampas and Prairies?
Ans: Grasslands provide vast open areas with nutrient-rich grass, making them ideal for grazing livestock like cattle.

(v) Why are there fewer trees in the grasslands compared to forests?
Ans: The climate, frequent fires, and grazing animals prevent trees from growing, allowing grasses to dominate instead.

True or False
