Ecosystem ecology is a branch of ecology that focuses on the interactions between living organisms and their physical environment within an ecosystem. This field of study examines the flow of energy and nutrients through ecosystems, as well as the dynamics and relationships of different species within a given environment. Ecosystem ecologists study how ecosystems function, how they respond to disturbances, and how they are affected by human activities such as deforestation, pollution, and climate change. By understanding these complex relationships, ecosystem ecology plays a crucial role in informing conservation and management efforts aimed at preserving and restoring ecosystems.
