- 1. Limnology is the study of inland water systems, including lakes, ponds, rivers, and wetlands. This branch of science explores the physical, chemical, biological, and ecological aspects of freshwater environments. Limnologists investigate the interactions between aquatic organisms and their surrounding habitats, as well as the impact of human activities on water quality and ecosystems. By studying the dynamics of these aquatic systems, limnologists help to inform conservation and management strategies to protect and sustainably utilize our valuable freshwater resources.
