The coal is classified as organic sedimentary rock because the basis for its formation is the organic matter. It is a rock that is formed on the basis of dead organic matter from the Carboniferous, mostly of trees that existed in this period.

Identical feature is present in the organisms that reproduce through asexually means from only one parent so the identical shape and structure is not the cost of sexual reproduction.
