The biosphere is the global ecological system integrating all living beings and their relationships, including their interaction with the elements of the lithosphere, geosphere, hydrosphere, and atmosphere.
  • The lithosphere consists of the earth's crust and upper part of its mantle.
  • The atmosphere is what we call 'the air,' or the mixture of gases held around the earth by its gravitational pull.
  • The hydrosphere is the total sum of all of earth's water in any form, whether it's on the ground as liquid or ice, or in the clouds as water vapor.
The biosphere is the fourth sphere and consists of the places where life can be found. Since life exists in the air, on and in the earth, and on and in water, the biosphere overlaps, connects, and influences all the other spheres - and they all affect the biosphere.

Biosphere is a term used to represent a small zone of Earth, where the lithosphere, hydrosphere, and atmosphere come in contact with one another.

The biosphere refers to the part of the Earth's surface and atmosphere where living organisms exist. It is the layer of the planet that supports life and encompasses various ecosystems, including forests, deserts, oceans, and grasslands. This term is used to describe the interaction between living organisms and their environment.

Explanation:
The biosphere is a complex and interconnected system that includes the lithosphere, hydrosphere, and atmosphere. These three components interact with one another and create a unique environment that sustains life on Earth.

1. Lithosphere:
The lithosphere refers to the solid outer layer of the Earth, including the crust and uppermost part of the mantle. It is the rigid, rocky part of the planet that provides a foundation for landforms and supports various ecosystems. In the biosphere, the lithosphere plays a crucial role as it provides the physical substrate for life and forms the basis for the formation of soils and landforms.

2. Hydrosphere:
The hydrosphere encompasses all the water on Earth, including oceans, lakes, rivers, groundwater, and even atmospheric water. It is an essential component of the biosphere as it supports aquatic ecosystems and is crucial for the survival of all living organisms. The hydrosphere interacts with the lithosphere and atmosphere through processes such as weathering, erosion, and the water cycle.

3. Atmosphere:
The atmosphere is the layer of gases that surrounds the Earth. It consists of various gases, including nitrogen, oxygen, carbon dioxide, and water vapor. The atmosphere plays a vital role in the biosphere as it provides oxygen for respiration, regulates temperature, and protects living organisms from harmful solar radiation. It interacts with the lithosphere and hydrosphere through processes such as weather patterns, climate change, and the exchange of gases.

4. Interaction in the Biosphere:
The biosphere is the zone where the lithosphere, hydrosphere, and atmosphere interact with one another. This interaction is crucial for the exchange of nutrients, energy flow, and the maintenance of ecological balance. For example, plants obtain nutrients from the soil (lithosphere), water from the hydrosphere, and carbon dioxide from the atmosphere to carry out photosynthesis. Similarly, animals depend on these interconnected systems for food, water, and shelter.

In conclusion, the biosphere represents the small zone on Earth where the lithosphere, hydrosphere, and atmosphere interact. It is the layer of the planet that supports life and encompasses various ecosystems. The interaction between these components is vital for the survival and functioning of living organisms.
