Answer 2

Hunger is a biological response that tells us that we have eaten less than normal. We feel hungry when our stomach contracts and our brain cells detects it by the presence of nutrients and glucose in blood and send signals to stomach to start contraction which makes us hungry.

Other than that time also triggers hunger. For example, some people start to feel hungry at a particulate time because it is usual time to eat such as lunch time or dinner.

Moreover, sigh and smell of food also makes us hugry.
