HeaterWinterBeforeFeedback.jpg

① Let's say, winter came. Room temperature becomes low due to the winter chill. A heater increases room temperature. These are in the opposite direction (blue).


HeaterWinterAfterFeedback.jpg

② Since these are in the opposite direction, negative feedback facilitate (red) the heater (function, such as by turning the power on). Because of this, the room temperature-increasing effect of the heater strengthen, and the decrease in room temperature (blue downward unfilled arrow) fades away (decreased room temperature increases to the baseline room temperature).



This simply says, when the room temperature is decreased (during winter), heaters are used. In the present "step-by-step study of life sciences", let's call such control bluered> negative feedback.

Challenge Quiz

1.

Due to the winter coldness, room temperature becomes high low , and a heater raises lowers room temperature.

Because these are in same direction opposite direction , negative feedback inhibits facilitates the heater (function).

2.

When room temperature is low, negative feedback inhibits facilitates heater (function).
