There can be a lot of questions about whether you are talking about raw or cooked chicken, etc. but taking the question at face value...chicken rots much quicker than ham, because ham is cured, a process that extends the edible life of the ham for a long time.
All other things being equal, chicken will spoil faster.
cow milk rots faster
Jelly rots faster because the jelly contains fresh fruit.
Since Coke or Pepsi decays teeth the most i think those 2 sodas will decay a bone faster.
because it just rots faster
It rots faster outside of a refridgerator.
It rots faster in the light.
Vegetables
lemon juice because the acid from the lemon rots the bone from the inside out
strawberry
none of them
Definitely a tomato.
