What do all living organisms require to survive, as highlighted in the description of the water cycle?

Glucose
Water
Oxygen
Minerals

The correct answer is: Water

All living organisms require water to survive because it is essential for various biological processes. Water is a vital component of cells, where it serves as a universal solvent, facilitating chemical reactions necessary for life. It also plays a crucial role in maintaining homeostasis, transporting nutrients and waste products, and regulating temperature. In the context of the water cycle, organisms depend on water for hydration, growth, and overall functioning. While glucose, oxygen, and minerals are also important for life, they are not as universally critical as water, which is needed by all living organisms for survival. Water's unique properties make it indispensable in biological systems, highlighting its fundamental role in sustaining life.
