Which food will rot the fastest Bananas tomatoes bread eggs or opened yogurt?

The food that will rot the fastest out of the options you listed is opened yogurt. Here's why:

* Opened Yogurt: Yogurt is a perishable dairy product that is highly susceptible to bacterial growth once opened. The introduction of air and the presence of moisture create an ideal environment for bacteria to multiply quickly, leading to spoilage.

* Bananas: While bananas do ripen and eventually become overripe, the process is relatively slow. They can last for a few days to a week depending on their ripeness level.

* Tomatoes: Tomatoes, like bananas, have a fairly long shelf life if stored properly. They can last for several days or even weeks.

* Bread: Bread can last for several days, especially if stored properly in a cool, dry place. However, mold can start to grow after a few days.

* Eggs: Eggs can last for several weeks in the refrigerator. While they don't "rot" in the same way as other foods, their quality deteriorates over time.

Therefore, opened yogurt is the most perishable option and will spoil the fastest.
