Explanation:

An open system exchanges both matter and energy with its surroundings. Plants take in carbon dioxide, water, and sunlight (energy) and release oxygen and organic matter (matter). A closed system only exchanges energy. Decomposition system and manufactured system are not standard terms for this classification.

D. open system
