WebFigure 2.8 shows how positive and negative feedback affect a population. With the positive feedback loop, an increase in the population leads to more births, which increases the population even more. With the negative feedback loop, an increase in the population reduces the food supply. Less food means more deaths and fewer births.

Negative feedback prevents a physiological variable or a body function from going beyond the normal range. It does this by reversing a physiological variable change (stimulus) once the normal range is exceeded. The components of a negative feedback … WebThey do this through positive and negative feedback loops. Maintaining homeostasis requires that the body continuously monitors its internal conditions.
