HeaterSummerBeforeFeedback.jpg

① Let's say, summer came. Room temperature is increased due to the summer heat. A heater increases room temperature. These are in the same direction (red).

② Since these are in the same direction, negative feedback inhibits (blue) the heater (function, such as by turning the power off). Because of this, the room temperature-increasing effect of the heater weakens, and the increase in room temperature (red upward unfilled arrow) fades away (increased room temperature decreases to the baseline room temperature).


This simply says, when the room temperature is increased (during summer), heaters are not used. In the present "step-by-step study of life sciences", let's call such control redblue negative feedback.

Challenge Quiz

1.

Due to the summer heat, room temperature is increased decreased , and a heater increases decreases room temperature.

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

2.

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