The significance of the water cycle in ecosystems lies in its role in water distribution, necessary for life. This continuous cycle involves evaporation, condensation, precipitation, and runoff, linking terrestrial and aquatic systems. It maintains habitat stability and supports photosynthesis, which is vital for plant growth and, consequently, animal life. The water cycle also influences climate patterns and weather events, affecting ecosystem health and function. Proper functioning of the water cycle is essential for maintaining biodiversity, nutrient cycling, and overall ecosystem resilience against environmental changes.
