Aquatic ecology is the study of ecosystems found in water environments, including oceans, rivers, lakes, and wetlands. It examines the interactions between living organisms, such as fish, plants, and microorganisms, and their physical surroundings. This field helps us understand how these ecosystems function and the importance of biodiversity within them. Researchers in aquatic ecology also investigate the impact of human activities, such as pollution and climate change, on water habitats. By studying these effects, scientists can develop strategies to protect aquatic ecosystems and ensure the sustainability of resources like freshwater and marine life.
