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
In the grassland there are less number of trees and places to hide. The animals are vulnerable to predators (e.g. lions, tigers, wolves etc.). They can only survive and escape if they run very fast. Therefore, speed is important for survival in the grasslands for animals. We can take the example of deer. It is often attacked by loin and tiger and if they don’t have speed, they cannot survive.
