NegFeedBackBasic/ControlOfHeaterToWinterChill

POINT!

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

動画と音声での説明

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

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 strengthens, 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 blue→red negative feedback.
