Graphite is one of the allotropic forms of carbon.
Actually the plants and animals will die and deacy on the bottom of the earth. the temperature of the earth and the change in the climate will convert the decays in to liginite, coal, Antheracite, graphite, etc.,
the conversion will take millions of years.

Where Does Graphite Come From

Graphite is usually nearly pure carbon. It displays basal cleavage due to its crystal habit. Its a very soft mineral ranging from 1-2 on Mohs scale. It can be found in a lot of places since it is carbon and its associated with a lot of other common minerals. Currently China is the top producer of graphite.

Graphite (named by Abraham Gottlob Werner in 1789 from the Greek γραφειν (graphein): "to draw/write", for its use in pencils) is one of the allotropes of carbon. Unlike diamond, graphite is an electrical conductor, and can be used, for instance, as the material in the electrodes of an electrical arc lamp. Graphite holds the distinction of being the most stable form of solid carbon ever discovered. It may be considered to be the highest grade of coal, just above anthracite, although it is not normally used as fuel because it is hard to ignite.
The name "graphite" is also sometimes used to refer to carbon fibre or carbon fibre reinforced plastic.
