Explain why speed is important for the survival of animals like deer which live in grassland habitats.

Adaptation:

1. Adaptation is a long-term behavioral or physical modification in a living organism such as plants and animals that helps it survive in its habitat better.

Adaptation in deer:

1. Grasslands are regions with abundant grass populations.
2. Lion, Tiger, etc. are the commonly found predators of grassland that preys on animals such as deer.
3. Due to the absence of big trees, the chances of catching prey by a predator are quite high.
4. Therefore, deer adapt themselves by increasing their speed to escape the predators and thus protect themselves.
5. The increased speed of the animal provides a chance of survival to the weakest class of animals in the grasslands.
