The hydrological cycle is significant for ecosystems because it regulates the distribution and availability of water essential for all living organisms. It involves processes such as evaporation, condensation, precipitation, and runoff, cycling water through various forms. This cycle supports plant growth, influences climate patterns, and sustains wildlife habitats. Moreover, it ensures the circulation of nutrients within ecosystems, facilitating ecological interactions and maintaining biodiversity. Disruptions in this cycle can lead to droughts, floods, and habitat loss.
