Biosphere: Understanding the Concept

What Is The Biosphere?

• The biosphere is a group of spheres or layers where life on Earth is possible.
• The term 'biosphere' combines 'bio' (meaning life) and 'sphere' (meaning a round object).
• The biosphere is the place where life occurs on planet Earth, encompassing the entire planet.

Components Of The Biosphere

• The biosphere consists of multiple spheres or layers, including the lithosphere, atmosphere, and hydrosphere.
• The lithosphere refers to the soil and rocks on the earth's crust and sea bottom.
• The atmosphere is composed of layers of different gases that surround Earth.
• The hydrosphere includes all the water on Earth, such as oceans, lakes, rivers, and underground water.

Characteristics Of The Biosphere

• The biosphere contains living organisms, including plants, animals, and microorganisms.
• Microorganisms are simple, unicellular organisms that are too small to be seen with the human eye, requiring a microscope to observe.
• The biosphere also includes dead organic matter.
