All these living organisms exist in forests, grasslands, soil, and water bodies as part of the natural environment.
What is the name given to this sphere?
The sphere that supports all living organisms (plants, animals, and microorganisms) is called the Biosphere.

Important Features of the Biosphere:
- Supports Life – It includes all ecosystems where life exists, such as forests, oceans, rivers, grasslands, and deserts.
- Interaction of Spheres – The biosphere interacts with the lithosphere (land), atmosphere (air), and hydrosphere (water) to sustain life.
- Diverse Ecosystems – It includes terrestrial (land) and aquatic (water) ecosystems, each with unique plants and animals.
- Food Chain & Balance – It maintains the food chain and ecological balance by supporting different species at various levels.
- Climate Regulation – Plants and animals play a key role in oxygen production, carbon absorption, and climate stability.
Thus, the Biosphere is the life-supporting zone of Earth, where different organisms coexist in a delicate balance!
FAQs
The Biosphere is the life-supporting zone of Earth, where all living organisms—plants, animals, and microorganisms—exist and interact with their environment.
The Biosphere includes:
✔ Living organisms (plants, animals, bacteria, fungi)
✔ Ecosystems (forests, oceans, deserts)
✔ Interaction with land (lithosphere), air (atmosphere), and water (hydrosphere)
It provides:
✔ Oxygen for breathing
✔ Food and shelter for organisms
✔ Climate regulation by absorbing CO₂
✔ Balance in ecosystems through food chains and natural cycles
Activities like deforestation, pollution, and climate change harm the Biosphere by destroying habitats, reducing biodiversity, and disrupting natural cycles.
✅ Plant more trees
✅ Reduce pollution
✅ Protect wildlife and ecosystems
✅ Use natural resources responsibly
By preserving the Biosphere, we ensure a healthy planet for future generations!
