Biosphere Definition. The biosphere, which includes the ground and the air, is characterized as the region of the planet where organisms live. The biosphere is defined as the region on, above, and below the Earth’s surface where life exists.
Biosphere, relatively thin life-supporting stratum of Earth’s surface, extending from a few kilometers into the atmosphere to the ocean’s deep-sea vents. This global ecosystem continuously cycles matter. It is composed of organisms (biota) and the abiotic (nonliving) factors from which they derive energy and nutrients.
A false color composite of global oceanic and terrestrial photoautotroph abundance, from September 2001 to August 2017. Provided by the SeaWiFS Project, NASA/Goddard Space Flight Center and ORBIMAGE. [citation needed]The biosphere (from Ancient Greek βίος (bíos) 'life', and σφαῖρα (sphaîra) 'sphere'), also called the ecosphere (from Ancient Greek οἶκος (oîkos) 'settlement, house', and σφαῖρα (sphaîra) 'sphere'), is the worldwide sum of all ecosystems.It can also ...
Mar 6, 2023 · The biosphere is where living organisms are found on, above, and below the Earth’s surface. It is thus one large ecosystem characterized by biotic (living things), abiotic (non-living) factors, and energy working together as a single unit.
Dec 4, 2023 · The biosphere is the region where life exists along with the air and the land. It is the combination of all types of ecosystems on Earth which integrates all the biological communities and their interactions or relationships with the environment.
Oct 19, 2023 · 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.The atmosphere is the layer of air that stretches above the lithosphere. The Earth’s water—on the surface, in the ground, and in the air—makes up the hydrosphere. Since life ...
Jun 12, 2022 · Origin and Evolution of Biosphere. About 3.8 billion years ago, the early prokaryotes thrived in a biosphere without oxygen. Eventually, some of these organisms evolved into ones capable of utilizing light, water, and carbon dioxide to create chemical energy-rich compounds while producing oxygen molecules as a byproduct.
The biosphere is also known as ecosphere. It is the worldwide sum of all ecosystems, incorporating all life forms and their relationships, which includes their interactions with the elements of the atmosphere, hydrosphere, and lithosphere.. Simply put, the biosphere is the space on or near the Earth’s surface where land, air, and water interact with each other to support life.
INTRODUCTION. The biosphere is the region of the earth that encompasses all living organisms: plants, animals and bacteria. It is a feature that distinguishes the earth from the other planets in the solar system. "Bio" means life, and the term biosphere was first coined by a Russian scientist (Vladimir Vernadsky) in the 1920s.
biosphere, Relatively thin life-supporting stratum of the earth’s surface, extending from a few miles into the atmosphere to the deep-sea vents of the oceans.The biosphere is a global ecosystem that can be broken down into regional or local ecosystems, or biomes. Organisms in the biosphere are classified into trophic levels (see food chain) and communities.
