Answer:
negative feedback
Step-by-step explanation:
the control of blood sugar level is good example of negative feedback mechanism. the whole loop of balancing blood glucose level is constantly in motion i.e one process triggers another process.
Glucagon causes blood-glucose levels to increase until they reach a high enough level for glucagon production to stop, and insulin production to start. This process is called a negative feedback loop, where the result of a process turns off the process.
