What is called the biosphere? What are the features of the biosphere? What living organisms live in the biosphere?

The biosphere can be called the shell of the earth. The biosphere is completely inhabited by living organisms. At the moment, the inhabitants of the biosphere are more than three million species of animals, plants, fungi. This includes a person. The biosphere is located in the upper layers of the lithosphere, in the hydrosphere and in the lower layers of the atmosphere. Living organisms live and develop in the upper layers of the lithosphere. Not a single living organism can exist outside the zone of the biosphere, although man strives to explore space, but so far only our biosphere is favorable for the life of all living things.
