How a deer is adapted to live in forest and grassland habitat?

The meaning of adaptation implies how a species changes its body and behaviour to better suit its natural environment. Deers have the following adaptation for forest and grassland habitat:

1) They have strong teeth to chew hard stems.

2) They have long ears to hear the movements of the predator.

3) The eyes on the sides of their head allow them to look in all directions for danger.

4) Their speed helps them to run away from predators.
