One of the following processes is not a step involved in the water cycle operating in nature:

The correct option is Photosynthesis.

Explanation:

Water cycle: The water from the ocean and surface of the earth goes into the air as vapour returns as rain, hail or snow and finally goes back to the oceans. The circulation of water in this manner is known as the water cycle.

• Evaporation, Transpiration, Condensation and Precipitation are the major process of the water cycle.

• The sun is the driving force behind the water cycle.

The precipitation comes down to the earth in liquid form is rainwater.

Additional Information

Photosynthesis: The leaves have a green pigment called chlorophyll. It helps leaves to capture the energy of the sunlight. This energy is used to synthesise (prepare) food from carbon dioxide and water. Since the synthesis of food occurs in the presence of sunlight, it is called photosynthesis.

• In the presence of sunlight Carbon dioxide + water → Carbohydrate + oxygen.
• Some plants, green algae, and cyanobacteria can perform photosynthesis.
• The process of photosynthesis is commonly written as

• 6CO2 + 6H2O + Sun-Light → C6H12O6 + 6O2
