Detailed explanation-1: -The Biosphere–contains all the planet’s living things. This sphere includes all of the microorganisms, plants, and animals of Earth. Within the biosphere, living things form ecological communities based on the physical surroundings of an area. These communities are referred to as biomes.

Detailed explanation-2: -Both the geosphere and hydrosphere provide the habitat for the biosphere, a global ecosystem that encompasses all the living things on Earth. The biosphere refers to the relatively small part of Earth’s environment in which living things can survive.

Detailed explanation-3: -The biosphere, also known as the ecosphere, is the Earth’s dynamic biological epidermis of unknown dimensions. It is the natural habitat of living organisms. It is made up of the lithosphere’s surface, a lower portion of the atmosphere, and the hydrosphere. The biosphere is the world’s ecological system as a whole.

Detailed explanation-4: -The biosphere includes all life on our planet. It is not only all the things that are living, but also the remains of organisms that have died and not yet decomposed. It also includes the regions of the other parts of the Earth system (atmosphere, hydrosphere, geosphere) occupied by living organisms.

Detailed explanation-5: -The biosphere includes the outer region of the earth (the lithosphere) and the lower region of the atmosphere (the troposphere). It also includes the hydrosphere, the region of lakes, oceans, streams, ice and clouds comprising the earth’s water resources.
