Micro-organisms include both heterotrophic (consumers), autotrophic (primary producers or photosynthetically active organisms) and mixotrophic (mixed nutritional strategy) prokaryotes (bacteria) and microbial eukaryotes.

The objective of this project was to obtain new data on the effect of hypodynamy, hypergravity and microgravity on quail, which could be used in the future as a higher heterotrophic link in autonomous closed ecosystems during long-term stays of humans on orbital and planetary stations.
