Are non carbon based life forms possible? Why or why not? Give at least two reasons to support your answer.

 No, non carbon based life forms are not possible.  According to scientists, all living things, like plants and animals, are composed of carbon.  Without carbon, all living will not survive.  Carbon can bond to with other elements, especially oxygen, hydrogen and nitrogen, which forms molecules.  These elements are very important for living organisms.  Protein, fat, carbohydrates, and nucleic acids are important molecules that contains carbon and allow the living organisms to receive energy, live, and develop.  Carbon, oxygen, and hydrogen forms carbohydrates, which is the building blocks of life.  With these reasons, I conclude that non carbon based life forms are not possilbe.
