Biosphere definition

Answer 1

The biosphere refers to the global sum of all ecosystems; it is the zone of life on Earth, where interactions occur between living organisms (flora and fauna) and their environment (land, water, and atmosphere). Encompassing all living beings and their relationships with the elements of the environment, the biosphere is vital for sustaining life. It includes various habitats, such as forests, deserts, mountains, oceans, and wetlands, and operates within a system of energy flow and nutrient cycling that supports diverse biological communities. The biosphere plays a crucial role in regulating climate and maintaining the balance of ecosystems.
