The analogy of the price of pizza being set too high and customers going elsewhere is a clear example of negative feedback. The high price causes a decrease in sales, which is a negative response that causes the shop to lower their prices in order to try and attract customers back. This demonstrates to the students how a negative feedback loop works to regulate a system and restore balance. The other analogies are not as directly relevant to negative feedback loops and may confuse or distract the students from the main concept.
