How is ecosystem different from ecoregion?

An ecosystem refers to a community of living organisms interacting with each other and their physical environment, encompassing various biotic and abiotic components. In contrast, an ecoregion is a larger geographical area defined by specific climatic, geological, and ecological characteristics, which can contain multiple ecosystems. Essentially, while ecosystems focus on interactions within a specific area, ecoregions emphasize broader landscapes with similar ecological patterns and processes.
