Answer :
The given scenario where an animal plays dead to protect itself is an example of a response to the external stimulus of danger. In this case, the external stimulus is the danger posed by other animals, leading the animal to react by playing dead as a defense mechanism. This behavior helps the animal avoid further harm or potential threats by deceiving predators or other dangers.
Here's why it fits as a response to the external stimulus of danger:
1. **External Stimulus:** The danger presented by other animals is an external factor that triggers the response of playing dead. It is a threat from the environment outside the animal.
2. **Play Dead Response:** Playing dead is a survival strategy employed by some animals when faced with danger. By feigning death, the animal may trick predators into thinking it is not a threat or not worth pursuing, thus avoiding harm.
3. **Protective Mechanism:** Playing dead is a form of defense mechanism against external dangers. It allows the animal to escape or survive potentially life-threatening situations.
By correctly identifying the situation as a response to the external stimulus of danger, we can understand how animals adapt and respond to threats in their environment for survival.
