What and where is the biosphere quizlet?
the parts of the planet including land, water or atmosphere in which all life exists (It extends from about 8 km above the Earth’s surface down to 11 km below the ocean’s surface.)
What is Biosphere explain in detail?
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 rain forests and high mountaintops. Scientists describe the Earth in terms of spheres.
What are the two components of biosphere?
Components of Biosphere
- Lithosphere. The lithosphere is the terrestrial component of the biosphere. It consists of strong ground blocks like continents and Maldives.
- Hydrosphere. The hydrosphere is the biosphere’s aquatic component.
- Atmosphere. The atmosphere is the adjacent gaseous envelope of a planet.
What are the major components of biosphere?
Biosphere has three basic components. These are (A) abiotic (physical and inorganic) components; (B) biotic (organic) components and (C) energy components. Let us discuss about these three components in detail.
What are the four components of biosphere?
The biosphere is the portion of Earth where life occurs — the portions of the land, water and air that hold life. These parts are known, respectively, as the lithosphere, hydrosphere and atmosphere.
What are four biosphere components?
The biosphere is a global ecosystem composed of living organisms (biota) and the abiotic (nonliving) factors from which they derive energy and nutrients. Earth’s environment includes the atmosphere, the hydrosphere, the lithosphere, and the biosphere. Encyclopædia Britannica, Inc.
What are the limits of biosphere?
It extends vertically into the atmosphere to about 10 km, downward into the ocean to depths of about 10.4 km and into about 27,000 ft of the earth՚s surface where maximum living organism have been found.
What is the importance of the atmosphere?
The atmosphere protects living things from the Sun’s most harmful rays. Gases reflect or absorb the strongest rays of sunlight (figure below). The atmosphere shields Earth from the most harmful solar rays.

What are biotic and abiotic components of a biosphere?
Examples of abiotic factors are water, air, soil, sunlight, and minerals. Biotic factors are living or once-living organisms in the ecosystem. These are obtained from the biosphere and are capable of reproduction. Examples of biotic factors are animals, birds, plants, fungi, and other similar organisms.
Is virus biotic or abiotic?
Viruses are not living things. Viruses are complicated assemblies of molecules, including proteins, nucleic acids, lipids, and carbohydrates, but on their own they can do nothing until they enter a living cell. Without cells, viruses would not be able to multiply. Therefore, viruses are not living things.
