It's not difficult at all, especially since you can just add more CO2/nitrogen/water/oxygen if need be at any time using machines.

Even if you don't manage anything whatsoever, it's still easy. Pic related is my little terrarium ecosphere, it's got earthworms and isopods and snails and springtails and more, not to mention plants. I made it two and a half years ago by putting dirt in a jar, no other intervention except for every now and then I rotate it so sunlight hits it different. All the plants and animals were already in the soil as seeds or eggs, I have not opened that thing since the first time I closed it, and the lid forms an airtight seal.
