Question

Which of the following activities help in increasing the content of water vapour in air?

• A. Transpiration
• B. Evaporation
• C. Respiration
• D. All of the above

Answer 1

The correct option is D

All of the above

Transpiration, respiration and evaporation help in increasing the content of water vapour in the air. Evaporation is the process of a substance in a liquid state changing to a gaseous state due to an increase in temperature. Transpiration is the evaporation of water from plants. Respiration is defined as the movement of oxygen from the outside environment to the cells within tissues, and the transport of carbon dioxide in the opposite direction.
