Question 8. Explain, why speed is important for survival in the grasslands for animals that live there. (Hint: There are few trees or places for animals to hide in grasslands habitats.)
Answer As we look into grasslands habitats, there are fewer trees or few places for animals to ride and move from one place to another. When their enemy (for example: if carnivores attack herbivores) attacks they should run fast to reach the safer place to live their life. They lose their life if they are really slow. They can only survive and escape if they can run faster. Thus, the speed is the important factor for animals to survive in grasslands habitat as the speed makes them live their life.
