NO!!! It does not occur naturally. However, its mineral ores are very common. e.g. Haematite, Magnetite.
A control group is the group in which one attempts to keep everything the same as would naturally occur. This is done to be able to compare groups that have results to a standard reference.
Too many plants are edible to provide a short answer. Lots of plants are also toxic. Bacteria can make some of the toxic ones less toxic (chocolate), as can some processing steps (poke salad for example) Yes, caffeine occurs naturally, as do other alkaloids.

in there native state
