I think full live support with food production is unrealistic at TL7 and
overly optimistic at TL8.
I believe that this mostly depends on the size of the vehicle or
habitat. We already have evidence that full life support is available at
TL 0 if you use the surface of a sphere 6.3 Mm radius. :-)
Size does matter, but you also need organisms that are evolved or designed
for your ecosystem.
Building many habitats with the right starting components and see if
something harvestable evolves and start from scratch, where live dies
out would be an interesting experiment, but it would take really long.
And now my fist mental image, that i got from your post:
"In ancient times earth was barren, but then stone age humans came and
planted all the plants and set all the animals free and so the ecosystem
was built."
