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 habitat).
Answer.
In grasslands, there are very few trees to hide for animals from predators like lion and tiger. In small grasses, predators can easily locate their prey. So, these animals have to run fast to reach a safe place and escape from their predators. Thus, speed is important for survival in the grasslands for animals that live there.
