On Earth, life has evolved to fill almost every potential ecosystem we can find, even unimaginably inhospitable ones. Are there any plant or animals species that we know of from Earth that we could take to Mars that would have a solid chance of surviving there?

As I look at the images from Curiosity, I'm amazed at how barren of life Mars appears to be considering that in almost every part of Earth, we find that life has evolved to survive and usually thrive an enormous variety of conditions.  Seems like we must have something from Earth that could be used to 'seed' life on Mars so that, even if it took place over hundreds of thousands of years, it could eventually evolve and begin to fill out a Mars-specific ecosystem.  But what would they be?  Any ideas Reddit?

There are certainly some extremophiles mostly bacteria or archaea that could survive on mars. Some of these could potential use the minerals on mars to grow and reproduce, others could go into a state of cryptobiosis kinda like hibernation where they could survive almost indefinitely in a dormant state. These bacteria are found in some of the most extreme places on earth including the inside of hot springs, or at extreme depths under the oceans. One really interesting bacteria is Deinococcus radiodurans, which can withstand the extreme radiation of space as well as being able to survive in a vacume, survive dehydration, survive extreme acids, and can even repair its own DNA after being exposed to radiation. In fact whenever they send things to mars, the moon and other planets, NASA always takes extra precautions to sanitation the space craft and space instraments so that they do not contaminate other words with life from Earth.
