NegFeedBackBasic/ControlOfCoolerToSummerHeat

POINT!

When room temperature is increased, negative feedback facilitate cooler (function).

動画と音声での説明

① Let's say, summer came. Room temperature is increased due to the summer heat. A cooler decreases room temperature. These are in the opposite direction (blue).

② Since these are in the opposite direction, negative feedback faciltates (red) the cooler (function, such as by turning the power on). Because of this, the room temperature-decreasing effect of the cooler weakens, and the decrease in room temperature (red upward unfilled arrow) fades away (decreased room temperature increases to the baseline room temperature).

This simply says, when the room temperature is increased (during summer), cooler are used. In the present "Step-By-Step Study of Life Sciences", let's call such control red→blue negative feedback.
