NegFeedBackBasic/ControlOfCoolerToWinterChill

POINT!

When room temperature is decreased, negative feedback inhibits cooler (function).

動画と音声での説明

① Let's say, winter came. Room temperature becomes low due to the winter chill. A cooler decreases room temperature. These are in the same direction (red).

② Since these are in the same direction, negative feedback inhibits (blue) the cooler (function, such as by turning the power off). Because of this, the room temperature-decreasing effect of the cooler weakens, 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), cooler are not used. In the present "step-by-step study of life sciences", let's call such control blue→red negative feedback.
