Question

Which of the following process is not a step involved in water cycle operating in nature?

• A. Photosynthesis
• B. Evaporation
• C. Rain fall
• D. Nitrogen metabolism

Answer 1

Answer: (D)

Nitrogen metabolism

• The process of nitrogen metabolism is not involved in the water cycle. By the process of photosynthesis, plants absorb water from the soil. Through transpiration, they lose water back to the atmosphere through stomata.
• By the process of evaporation, water from water bodies is condensed leading to the formation of clouds.
• Clouds then shower rainfall that restores the water evaporated from water bodies and also the groundwater levels.

So, option D is the correct answer as all others are a part of the water cycle.
