What three systems interact to form the biosphere?

The three systems that interact to form the biOSphere are the atmosphere, hydrosphere, and lithosphere. The atmosphere provides essential gases, such as oxygen and carbon dioxide, necessary for life. The hydrosphere encompasses all water bodies, supporting aquatic ecosystems and influencing climate. The lithosphere, which includes soil and minerals, supplies nutrients and habitats for terrestrial organisms, creating a complex and interdependent network of life.
