CO2
Mars Atmosphere is made of 95% Carbon Dioxide (co2) and 3% nitrogen (n2)
If man were to colonize mars and terraform it (raising the temperature and creating an atmosphere, add oxygen and co2) mars could host life.
no because you need CO2 and you don't have that on mars but you do have sunlight which is also needed EDIT: Thursday September 27, 2012 Mars consists of 95.23% carbon dioxide (CO2). The only limiting factors is UV protection like Earth's ozone layer and liquid water. The answer is still NO, Not naturally. photosynthesis "may be" possible with man made habitats designed to protect from UV radiation. Mars has an abundance of CO2!
The primary reason Mars is so much colder than the Earth is that Mars receives less than half of the of the energy from the sun as Earth does. This is because Mars is further away from the sun than Earth is. Mars' atmosphere is over 90% CO2, but Mars' total atmosphere is only about 0.6% that of Earth. Meaning that Mars has very little atmosphere of any kind to speak of, and so its atmosphere provides only negligible insulation to the planet. The net result is a very cold planet with very low atmospheric pressure. From an Earthling's perspective, Mars is no more hospitable than the vacuum of space.
One of mars's poles is frozen water and the other pole is dry ice (frozen co2)
95.32% of the Martian atmosphere is Carbon Dioxcide.(aka CO2)
The atmosphere of Mars is almost entirely CO2.

CO2. That's carbon dioxide.
Mars
Both Mars and Venus have atmosphere made mostly of carbon dioxide. The atmosphere of Venus is much denser.

Mars used to be a creamy or beigy colour but has reacted with the CO2 in its atmosphere to become rusty
On earth, yes it is. Dry ice is a result of decompressed liquid CO2. Liquid CO2 requires a much higher compressed atmosphere. P.S. I hear it grows naturally on Mars.
