How does fruit decompose?

Fruits decompose because of all the sugars inside of them turn old and mouldy. This makes the fruit then also turn mouldy and bacteria is produced. This causes the fruit to decompose. Thank you very...

They just do.

I think because of the moisture in the air.

High sugar, salt or acid content creates a hostile environment for fungi and bacteria. Candying, salt curing and pickling are methods commonly used to preserve food.
