Detailed explanation-1: -The biosphere is made up of the parts of Earth where life exists. The biosphere extends from the deepest root systems of trees, to the dark environment of ocean trenches, to lush rainforests and high mountaintops. Scientists describe Earth in terms of spheres. The solid surface layer of Earth is the lithosphere.

Detailed explanation-2: -Part of the earth which supports life where living beings exists is called biosphere. The biosphere, is the layer of the planet Earth, where life exists.

Detailed explanation-3: -The biosphere supports all life on Earth, 3 to 30 million species of plants, animals, fungi, single-celled prokaryotes such as bacteria, and single-celled eukaryotes such as protozoans.

Detailed explanation-4: -The highest level of organization for living things is the biosphere; it encompasses all other levels. The biological levels of organization of living things arranged from the simplest to most complex are: organelle, cells, tissues, organs, organ systems, organisms, populations, communities, ecosystem, and biosphere.

Detailed explanation-5: -The biosphere is made of three parts, called the lithosphere, atmosphere and hydrosphere. The atmosphere is the air that living organisms use for respiration, and which supports life up to 2, 000 meters above the planet’s surface. The hydrosphere is the aquatic portion of the planet, all of which supports life.
