The water vapour released by organisms during respiration directly contributes to which environmental pool?

Correct answer: वायुमंडलीय जलवाष्प पूल (Atmospheric water-vapour pool)

Correct answer: B, the atmospheric water-vapour pool. During respiration, organisms use oxygen and release carbon dioxide and water. Some of this water leaves the body as vapour, especially in exhaled air; plants also release water vapour through transpiration. Because the vapour first mixes with the surrounding air, its direct destination is the atmosphere. Later, atmospheric water vapour may condense into clouds and return as precipitation, but those are later stages of the water cycle. A is wrong because groundwater forms when water infiltrates and percolates into the soil and rock, not immediately from released vapour. C is wrong because runoff is liquid water flowing over land after rain or melting. D is wrong because glacier accumulation requires snowfall and long-term freezing, not direct respiratory release. The key word is directly: respiration adds moisture to air first. Memory cue: respiration and transpiration both send water vapour upward into the atmosphere.
