Limnology is the study of inland bodies of water, such as lakes, rivers, streams, and wetlands. It focuses on the physical, chemical, biological, and ecological processes that occur in these aquatic systems. Limnologists study the unique characteristics of different water bodies, such as nutrient cycles, water quality, aquatic habitats, and the interactions between plants, animals, and microorganisms. This research helps to understand and protect freshwater ecosystems, inform management practices, and mitigate the impacts of human activities on aquatic environments.
