Question

in terms of energy, the earth is an open system, receiving energy from the sun as sunlight and emits energy back into space. this constant energy exchange with the external environment is a crucial aspect of open systems, influencing the earths climate and supporting life. which is the best example of a closed system? water treatment plant astronauts spacesuit a desert

Explanation:

A closed - system does not exchange matter with its surroundings. A water treatment plant takes in water and expels treated water, so it's not closed. A desert exchanges matter (e.g., water vapor, dust) with the atmosphere, so it's not closed. An astronaut's spacesuit is designed to be a self - contained environment where matter is not exchanged with the external space environment (while in space), making it a closed system.

Answer:
