It is a dynamic and interconnected system in which living organisms coexist and interact with the surrounding environment.
The biosphere is characterized by its diversity and complexity, as it comprises a wide range of organisms, such as plants, animals, fungi, and microorganisms, along with their habitats and ecological processes. It is a fragile and interconnected network, where each organism depends on others for survival and the balance of ecosystems.
The biosphere is not confined to a specific layer or depth, as life can be found across various parts of the planet, from the highest mountains to the deepest oceans, and from the hottest deserts to the coldest regions. It includes both terrestrial and aquatic ecosystems, ranging from forests, grasslands, and wetlands to lakes, rivers, and coral reefs.
Human activities have a significant impact on the biosphere, affecting its delicate balance and causing disturbances to ecosystems. The biosphere plays a crucial role in regulating Earth's climate, maintaining the availability of resources, and providing various ecosystem services vital for human well-being. Understanding and conserving the biosphere is vital to ensure the sustainable coexistence of all species and to preserve the intricate web of life on our planet.

The word "biosphere" has its origins in Greek. It is formed by combining two Greek words: "bios", meaning "life", and "sphaira", meaning "sphere" or "globe". The term was coined by geologist Édouard Suess in 1875, who used it to refer to the region of the Earth that is inhabited by living organisms. The concept was further developed by Russian scientist Vladimir Vernadsky in the 1920s, who defined the biosphere as the sum of all ecosystems on Earth. Since then, the term "biosphere" has been widely used to describe the area where life exists and interacts with the environment.
