How might research on the flow of matter and energy through ecosystems be helpful to creating a colony on mars?
spayn [35]

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.

The correct answer is C. Genetic analysis

Explanation:

In biology, two organisms have a phylogenetic relationship if they share a common ancestor and therefore have genetic similarities although in most cases there are also similarities in morphology, physiology, etc. However, two organisms might have similarities in morphology and physiology without genetic similarities. Due to this, if you need to determine whether two species are related or not the best method is a genetic analysis as only those organisms that share a common ancestor (phylogenetic relationship) are genetically similar.
