Question

how does the respiration helps in formation of water vapour to form clouds?

Answer 1

Water vapor is a by-product of respiration in plants and animals, plants also evaporates water through transpiration. When the air cools, molecules of water vapor in the air come closer together, too. Then, by the process of condensation the molecules of water vapor condense on tiny solid particles in the atmosphere. The tiny droplets of water result from condensation forms the clouds.
