Final answer:
The action of a thermostat sending a signal to an air conditioner to start cooling the room is known as feedback. The thermostat operates as a sensor in a homeostatic system to maintain the set point temperature.
Explanation:
When a thermostat reaches a certain temperature and sends a signal to the air conditioner to begin cooling the room, the action of sending the signal to the air conditioner is known as feedback. The thermostat acts as a sensor component in a homeostatic mechanism, where it detects the temperature and sends data to the control center, which in this case is the air conditioning system.
The control center then compares the current temperature to the desired set point and activates the air conditioner if cooling is necessary to bring the temperature back to the set point, thereby restoring homeostasis.
