Correct Answer is: Living organisms MUST be involved.
There is no first in a cycle but, most are comfortable thinking ice melts to water, water evaporates to vapor, vapor condenses and fall to earth as rain to snow.
A balanced water cycle is essential for maintaining ecosystems and supporting life on Earth. If the water cycle is imbalanced, it can lead to issues like droughts, floods, and disruptions in the distribution of water resources. This can have cascading effects on agriculture, wildlife, and human communities.
Without the water cycle there wouldn't be any water to water the crops and plants.Also we need the water cycle because it recycles our water so the fresh water we have can be drinkable. BUT must be cleaned!
water vapor, which then condenses as it cools with the rising altitude and falls as rain

Plants must complete their life cycle to fulfill their true purpose. For plant's life cycle to continue a seedling must live long enough to produce new seeds.
comes back down to earth as rain, snow, sleet, or hail, this cycle must be repeated
Energy in the form of heat must be added to the water.
Energy must be added to liquid water so that it reaches the boiling point, at which point the water will vaporize into water vapor.
To obtain the energy necessary for them to continue metabolism.
It should be balanced to regulate water. The amount of water should be maintained constant.
