Biosphere refers to a global ecological system that is composed of air, land, water, and all living organisms It is typically divided into two distinct parts: the atmosphere that is located above the Earth's surface, and the lithosphere which consists of the soil, rocks, and minerals. The biosphere is considered to be the global ecosystem where the interaction between living organisms and their non-living environment takes place.
The biosphere is an integral part of the planet and is essential for the function of other components such as the lithosphere, hydrosphere, and atmosphere. It is responsible for the maintenance of life on Earth by providing essential resources such as air, water, and food. As the biosphere is comprised of living organisms, it has the ability to self-regulate and adjust to changing environmental conditions. This is why it is often referred to as the "life-support system" of the planet.
Some of the best examples of biosphere include the following:
1. The Amazon Rainforest: The Amazon rainforest is the world’s largest rainforest and is located in South America. It is home to a rich array of diverse flora and fauna, and its forests are a major global source of oxygen. The Amazon rainforest has been an important source of food, medicine, and other natural resources for the people living in the region for centuries.
2. The Great Barrier Reef: The Great Barrier Reef is the largest living organism in the world and is located off the coast of Australia.

The reef is also a major source of tourism, as it draws in thousands of visitors each year.
3. Yellowstone National Park: Yellowstone National Park is a U.S. National Park located in Wyoming and Montana.

The park is an important source of biodiversity and is considered a World Heritage Site by UNESCO.
4. The Taiga: The Taiga is a boreal forest located across Northern Europe, North America, and Asia. It is the largest terrestrial biome and stretches for thousands of kilometers. The taiga is home to a variety of plants and animals, including moose, wolves, and wolverines.
5. The Arctic: The Arctic is a vast and remote region located around the North Pole. It is home to a wide range of animals, such as polar bears, seals, and whales, as well as a variety of plants. The Arctic is also home to indigenous people who depend on the land for their way of life.
