The correct statement about the water cycle is: Energy for the water cycle comes from the sun.
The sun’s energy drives processes such as evaporation and condensation, which are essential components of the water cycle. The other statements are incorrect because:
- Both plants and animals contribute to the water cycle (through processes like transpiration and respiration).
- Water does not have a specific starting and ending point; it continuously cycles through various forms (liquid, vapor, ice) and locations (oceans, atmosphere, rivers, etc.).
- Water changes form during the cycle (for example, from liquid to vapor during evaporation).
