Use your knowledge of photosynthesis and cellular respiration to explain why maintaining a healthy greenhouse is necessary for the long-term survival of the Mars Colony.

Also explain why the humans are just as crucial to the greenhouse.


Maintaining a healthy greenhouse is necessary for the long-term survival of the Mars Colony because humans need the energy stored in the plants to survive. We can not produce our own energy, so we rely on other sources. Humans are crucial to the greenhouse as well because the plants need the carbon dioxide humans produce.
