How is w ecosystem different from biospheres?

An ecosystem refers to a community of living organisms interacting with each other and their physical environment within a specific area, encompassing both biotic (living) and abiotic (non-living) components. In contrast, a biOSphere is a broader concept that encompasses all ecosystems on Earth, representing the global sum of all ecosystems where life exists. Essentially, ecosystems are smaller units within the biOSphere, while the biOSphere is the overarching system that includes all ecosystems and their interactions on a planetary scale.
