Answer:
Input is oxygen and output is carbondioxide or the movement.
Explanation:
These two systems i. e. scuba diver and scuba gear interacting with each other by giving oxygen to the individual and remove carbondioxide gas from the diver. The input of this system is oxygen that is required by the diver while the output is the carbondioxide gas produced by the diver or the movement of the diver. This scuba gear is responsible for the removal of carbondioxide gas from the system. This scuba gear enable us to stay in deep water for 60 minutes.
