NASA hаs lоng studied the cоncept оf а bioregenerаtive life support system, in which human astronauts could be supported by photoautotrophic organisms (e.g., plants and algae) in a sealed system that could allow long term space exploration and colonization, for example, a base on the moon or Mars.

Outside help is not allowed. 1. Assume a simple example of such a system containing astronauts (people) and plants. Considering their metabolic requirements, what are the inputs each would need in order to survive, and what are the outputs they would contribute to the other? 2. Considering the laws of thermodynamics, what overall input (from outside the system) would the system require in order to function? Please label your answers 1. and 2. and explain both parts fully and clearly.
