How Could We Sustain Life on Mars?

Even if we were able to sustain life on Mars, how could plants perform their photosynthesis enough to give us enough oxygen for survival?

More about the Atmosphere and Climate
Mars Oxygen ISRU Experiment, also known as MOXIE, is the new system for O2 (oxygen) production on Mars. "MOXIE collects CO2 from the Martian atmosphere, compresses and stores it, then electrochemically splits the CO2 molecules into O2 and CO. The O2 is then analyzed for purity before being vented back out to the Mars atmosphere along with the CO and other exhaust products," says http://mars.nasa.gov/mars2020/mission/science/for-scientists/instruments/moxie/.
How could we grow plants for more oxygen and food sources?
Using a UV light bulb would help the plants perform photosynthesis. With MOXIE, we could provide their CO2 (carbon dioxide) so they can help provide our O2 along with MOXIE. The negative effects of faux UV rays are that they are not as strong as the sun itself. Plants will not be able to perform photosynthesis as strongly as the Sun would let them. They might not be as healthy as plants here, but at least they would be getting the right amount of UV rays. The direct sunlight of Mars would kill a plant almost instantly. Mars may be frigid cold, it doesn't mean the sun shines lethally on the red planet. On Mars, the UV radiation is in extremely high levels which is severely dangerous to humans and plants. If a faux UV light is used, it would have to be set on special levels or the plants could die.

The "city" of Cydonia on Mars
Cydonia is a "city" on Mars. It has not truly been proven to actually be a city, but it is a theory. Cydonia is said to consist of a main city, face (right), the Bastion, 5-sided pyramid, wall, and spiral mound.
