Answer:

negative feedback

Explanation:

When the temperature of the body falls below the normal level, the shivering and surface capillary vasoconstriction that occurs is an example of a negative feedback mechanism of maintaining homeostasis.

The negative feedback mechanism act to counter the process that causes the deviation away from the normal body temperature, the set point. The sensor/receptor which is the skin, in this case, sends information to the control center (part of the brain), the control switch then activates the process of vasoconstriction and muscle shivering to raise the body temperature in case of abnormally low temperature or vasoconstriction and heavy breathing in case of abnormally high temperature.

The entire process is an example of negative feedback in homeostasis.

The model above is an example of negative feedback.

  • Negative feedback is a loop that feeds back to the input of the system's output, thereby reversing the change in such output.

  • The negative feedback allows creating an equilibrium (homeostasis) in the system.

  • This type of loop mechanism (negative feedback) is very common in nature.

In conclusion, the model above is an example of negative feedback.
