The biosphere refers to the parts of Earth where life exists, including all living organisms and their environments. This encompasses all ecosystems, from the deepest ocean trenches to the highest mountain peaks, and includes all the air, water, and land that supports life.
So, while "living ball" captures the essence of the biosphere as a sphere containing life, it doesn't fully capture the complexity and interconnectedness of all the living and non-living components within it.
