Banana rots the fastest in both room temperature and refrigerator and the apple rots the slowest in room temperature and refrigerator.

This means that the bananas don’t last really long before they rot and the apple lasts along time before it rots..

What makes food decay faster?

Some of the primary culprits are air, moisture, light, temperature, and microbial growth. Most fruits and vegetables spoil easily because of damage caused by microorganisms. Microorganisms such as bacteria, yeast and molds need water and nutrients for growth, energy and reproduction.

What are the three factors that cause bacteria to grow rapidly?

Conditions needed for bacterial growthMoisture – Bacteria need moisture in order to grow. … Food – Food provides energy and nutrients for bacteria to grow. … Time – If provided with the optimum conditions for growth, bacteria can multiply to millions over a small period of time via binary fission .More items…

What conditions make bacteria grow?

Bacteria can live in hotter and colder temperatures than humans, but they do best in a warm, moist, protein-rich environment that is pH neutral or low acid. There are exceptions: some bacteria thrive in extreme heat or cold. some can survive under highly acidic or extremely salty conditions.
