Is it true The term biosphere means living ball?

The term "biOSphere" does not literally mean "living ball." It refers to the global sum of all ecosystems, encompassing all living organisms and their relationships with the environment, including land, water, and the atmosphere. The Word is derived from the Greek "biOS," meaning life, and "sphaira," meaning sphere, which metaphorically conveys the idea of a "life zone" on Earth rather than a physical ball.
