Why is clouds is not living?

Clouds are not considered living because they lack the characteristics that define life, such as cellular structure, metabolism, growth, and reproduction. They are composed of water vapor and tiny water droplets or ice crystals, which are physical states of matter rather than biological entities. Additionally, clouds do not respond to stimuli in the way living organisms do, nor do they maintain homeostasis. Thus, while they are dynamic and can change form, clouds do not exhibit the essential traits of living organisms.
