Well, it's actually sort of tied between a banana and a pear. The banana definitely becomes black faster, but it sort of slows down rotting and the pear "out-rots" the banana. The pear would start rotting, and it'll be gushy. It becomes completely gushy and the juice runs out of it within 3 days. The banana however, will slow down and become a little blacker (or browner) day by day.
*I observed this with the fruit cut in half, wrapped in plastic wrap, and on a window sill under the sun.
Apple
The larger the fruit, the longer it takes.
Vegetables

A banana would rot faster because it is softer and attracts dirt and germs faster.
As posed, the question makes no sense. You cannot measure how much something rots.
Jelly rots faster because the jelly contains fresh fruit.
protect the seeds also as the fruit rots it provides some nourishment for the seedling
A banana i think.
well a banana because its softer
About 2-6 weeks. It depends on the kind of fruit and if you store it in the fridge or not!
