Explanation:
Animals play an important role in the water cycle by returning water to the environment. Let's see how different ways animals return water to the environment:
(i) Perspiring: Animals perspire or sweat to regulate their body temperature. This sweat contains water and is released into the environment, thereby returning water to the environment.
(ii) Drinking: Animals drink water to stay hydrated. After drinking water, they use it for various bodily functions like digestion, respiration, and circulation. The waste products from these functions are then excreted in the form of urine or feces, thereby returning water to the environment.
(iii) Urinating: As mentioned above, urine is one of the waste products excreted by animals. Urine contains water and other waste products like urea and salts. When animals urinate, they return water to the environment.
(iv) Breathing: Animals breathe in oxygen and exhale carbon dioxide. But, they also lose some water vapor during respiration. This water vapor is released into the environment, thereby returning water to the environment.
Therefore, the correct option to answer the sentence is (C) (i), (iii), and (iv) as animals return water to the environment by perspiring, urinating, and breathing.
