Understand the question: The problem is asking for the term that describes the part of Earth where life exists, encompassing land, water, and air.
Review the definitions of the provided terms: A 'Community' refers to all the populations of different species living and interacting in a specific area. A 'Biome' is a large geographic area characterized by specific climate conditions and particular types of plants and animals. An 'Ecosystem' includes all the living organisms in a particular area, along with the non-living components of their environment, interacting as a system.
Define the term 'Biosphere': The 'Biosphere' is the global ecological system that includes all living beings and their relationships, as well as their interactions with the Earth's lithosphere (land), hydrosphere (water), and atmosphere (air).
Compare the definitions: The term 'Biosphere' best fits the description of the part of Earth in which life exists, including land, water, and air, as it encompasses all ecosystems and living organisms on Earth.
