उत्तर
photosynthesis
Explanation:
The movement of water through ‘ living and non-living components of the biosphere or any other ecosystem is called the water cycle. Evaporation, transpiration and precipitation are involved in the cycling of water.
Photosynthesis is an anabolic process in which glucose is synthesised using simple inorganic substances like CO2 and H2O as raw materials in the presence of light and chlorophyll and with the release of oxygen as a by-product. No water molecules are released into the atmosphere in this process. In fact, water molecules are used up and fixed into carbohydrates. So, photosynthesis is not involved in the cycling of water.
