Explanation:
This research could help determine how efficient energy and matter transfer is through the ecosystem. Currently, it is known that this transfer is very inefficient with a mere 10% energy transfer captured in biomass from one trophic level to another. Most of the energy is lost to the environment mainly as heat energy.
It is, therefore, critical that research determines ways of drastically enhance this efficiency so as to be able to colonise Mars. It will be required that whatever humans grow/rear on Mars in small modified fields translate into a high transfer of energy when consumed by humans. This makes it tenable to sustain humans on the distant planet.
