Freshwater ecology is the study of the interactions between organisms and their environment in freshwater ecosystems such as rivers, lakes, wetlands, and streams. This field of study focuses on understanding the biological, chemical, and physical processes that occur in these environments and how they impact the biodiversity, structure, and functioning of aquatic ecosystems. Researchers in freshwater ecology investigate a wide range of topics, including water quality, nutrient cycling, species interactions, biodiversity, and the effects of human activities on these ecosystems. The ultimate goal of freshwater ecology research is to develop strategies for the sustainable management and conservation of freshwater resources.
