Detailed explanation-1: -The rabbit’s behavior is a response caused by an internal stimulus. When the rabbit saw the fox, it has occurred to the rabbit that it is a life threatening situation. These kinds of situation cause the organisms to display a fight-or-flight response.

Detailed explanation-2: -In the wild, rabbits’ natural predators include foxes, birds of prey, weasels, and stoats. In the wild, rabbits are always on high alert. When they sense danger rabbits will quickly run and hide away in their burrows or tunnel down into undergrowth for protection.

Detailed explanation-3: -Any unusual sight, smell or sound likely will cause him to twitch his ears, sniff the air and turn his head toward the stimuli. If no danger is detected, the rabbit likely will resume his activity; whereas, if he senses danger ahead, he’ll likely react accordingly.

Detailed explanation-4: -There is a natural (and complicated!) predator-prey relationship between the fox and rabbit populations, since foxes thrive in the presence of rabbits, and rabbits thrive in the absence of foxes.

Detailed explanation-5: -Rabbits are foreleg short and long back legs, and they have strong muscles and tendons, which make them run faster. In addition, rabbits can also stop suddenly while running, turn sharply or run back to escape chase in a zigzag motion (Firestone and Warren, 2010) .
