Studying freshwater ecosystems is significant in ecology because these systems are vital for biodiversity, providing habitat to diverse flora and fauna. Freshwater ecosystems, including rivers, lakes, and wetlands, also support essential services, such as water supply, flood regulation, and nutrient cycling. Their health is indicative of overall environmental quality and climate change resilience. Understanding these ecosystems aids in conservation efforts, as they face threats from pollution, invasive species, and climate change. Protecting freshwater ecosystems is crucial for maintaining ecological balance and human well-being.
