Solution
Biological water cycle:
Here, the living organisms, i.e., plants and animals, consume water from and return it to the global water cycle. Plants take up water from the soil or water reservoir and release it back in the form of water vapours by the process of transpiration. Animals take water from water reservoir or with food and return it to the air as vapours by respiration and to the soil in the form of fluid by excretion.
Dead and decayed organisms also add water to the environment. Water vapours formed by transpiration and respiration form clouds and enter the global water cycle. Water returns to the soil and reservoir in the form of rain to be reused. This completes the water cycle.
