Q8 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, mainly grasses are found. Trees are very few in number. Predators
such as lion, tiger, etc. that feed upon other animals are commonly found in these
regions. It is very easy for these predators to locate their prey in the grass. Therefore, to
protect themselves from these predators, animals adapt themselves by increasing their
speed. The increased speed of the animal helps the weaker animals to escape their
predator, thereby protecting themselves and increasing the chances of their survival.
