Biosphere

The biosphere is the global ecological system integrating all living beings and their relationships, including their interaction with the elements of the lithosphere, hydrosphere, and atmosphere. It includes all the ecosystems on Earth, from the deepest ocean trenches to the highest mountains.

Key Concepts

• Living Organisms: The biosphere is made up of a diverse range of living organisms, including plants, animals, fungi, and microorganisms.
• Ecological Relationships: Within the biosphere, there are complex relationships between different species and their environments.
• Environmental Interactions: The biosphere interacts with the geosphere (lithosphere), hydrosphere, and atmosphere, influencing and being influenced by these components.
• Biogeochemical Cycles: The biosphere plays a crucial role in the cycling of nutrients and elements such as carbon, nitrogen, and water.
