Yes, there can be non carbon based life forms; although none yet have been discovered; there is much speculation about the possibility of silicon based life forms due to certain similarities to carbon at the atomic level.
No. There would be no sun or stars without hydrogen and so none of the heavier elements would be formed. All life forms on earth are based on carbon - a non-metal. Most of them conatin organic compounds which are mainly based on non-metallic compounds. The need to breath oxygen (a non metal).

Carbon forms calcium carbide and carbon tetrachloride.
The nonmetal carbon forms the basis of life. The carbon compounds made by living things are said to be organic. Organic compounds not only contain carbon, but also hydrogen. The most common elements found in living things are carbon, hydrogen, oxygen, nitrogen, phosphorus, and sulfur. All of these elements combine in various ways to produce thousands of organic compounds. The study of the chemistry of living things is called biochemistry.
All organic compounds contain carbon; most inorganic compounds doesn't contain carbon.
After discovering non-carbon based life-forms at the deepest depths of our own planets' oceans, we are faced with the possibilty that life could exist on other planets even though they might or do possess atmospheres unsuited to the conventional carbon-based forms of life as we know them here on earth

carbon (C)
Carbon forms calcium carbide and carbon tetrachloride.
Carbon can be organic and non organic.
Carbon is a non metal.It forms covalent bonds with other elements.
It is mainly carbon in the form of graphite.
Everything organic is made of carbon, a non-metal. There are also other things, but carbon-based objects are the most common. Anything that's organic is carbon-based. Plants, most clothing, everything you eat, and wood is organic (and thus carbon-based).

no, everything is not... people give of carbon, while plants give us oxygen.. that's how we are living today.. trees and plants give us air to live Anything organic on our planet is made of Carbon. (*until recently) We are carbon life forms, as well as all plants and animals. As the other poster mentioned, Plants make oxygen but your question was what is the plant made of, which is carbon. Although Amazingly... NASA has recently discovered a non-carbon life form which uses arsenic in its makeup. http://www.theblaze.com/stories/nasas-big-announcement-scientists-discover-arsenic-based-life-form/
graphite is a form of carbon that forms in layers which is why it is able to be used in pencils, because the layers can slide off and get left on the page. Anyway carbon is a non-metal so graphite is a non-metal.
