How might cycling of water around earth change if living things were not found on this planet?? please help- I’m struggling a lil

Though they don't contribute as much as plants, animals still supply some of the water present in the water cycle. Animals contribute water mainly through breathing, perspiration and urination.

When animals breathe, their warm lungs fill with air. Inside the lungs, some of that air condenses into water vapor. When an animal exhales, they release more water vapor than they breathed in, which adds to the water present in the water cycle.

Many animals also sweat to cool down. When droplets of sweat evaporate from the surface of an animal's skin, they take a bit of the animal's body heat with them. They also turn into water vapor and enter the water cycle, just like water evaporating from plant leaves.

When animals consume water, they urinate to expel the excess, which then then evaporates and re-enters the water cycle. Even animal dung contains some water which may re-enter the cycle in the same way.

Though trees represent the biggest living contributors to the water cycle, animals also play a valuable role in recycling Earth's water. Without living creatures, the water cycle’s effectiveness diminishes, and less water recycles. Though often not included in the explanation of the water cycle, all living organisms contribute to it in their distinctive ways.
