Answer 1

The correct response is:

a closed system; energy is exchanged with the surroundings and not lost.

In the context of sustaining human life on Mars, a closed system would ideally recycle air, water, and food to minimize the need for constant resupply from Earth, while still allowing energy (like sunlight) to be exchanged with the environment.
