Question

Which scenario is an example of a negative feedback loop?\

a)When body temperature increases, sweat is produced as a cooling agent to lower body temperature.
b)In some parts of the world, birth rates are far exceeding death rates, which has led to overpopulation.
c)Ice reflects sunlight much better than water. A warmer atmosphere is turning ice to water, which is absorbing more of the Sun’s energy.
d)A warmer atmosphere is leading to warmer oceans. A warm ocean releases more carbon dioxide, which traps more heat in Earth’s atmosphere.

Answer 1

When body temperature increases, sweat is produced as a cooling agent to lower body temperature.

Step-by-step explanation:

Answer 2

a)When body temperature increases, sweat is produced as a cooling agent to lower body temperature.

Negative feedback loop is a state where an event is monitored and regulated to have an optimal level. For instance, in this given example, when body temperature increases over 37C, to normalize the body temperature sweat is produced by the skin.
