The biosphere is a global ecosystem made up of living organisms (biota) and the nonliving (abiotic) factors that provide them with energy and nutrients. The biosphere is a narrow zone on the surface of the earth where soil, water, and air combine to sustain life. Life can only occur in this zone.
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.
By the most general biophysiological definition, the biosphere is the global ecological system integrating all living beings and their relationships, including their interaction with the elements of the lithosphere, cryosphere, hydrosphere, and atmosphere.
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.
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.
Dec 4, 2023 · The biosphere is the region where life exists along with the air and the land. Biosphere is the combination of all types of ecosystems on Earth.
Jan 28, 2024 · Last Updated : 28 Jan, 2024. Biosphere is the region of the earth where life can exist and grow. It is also known as the Ecosphere, which means constitution of all the ecosystems existing worldwide. Let’s learn about Biosphere in detail, including its components, reserves, and some related facts.
Jun 12, 2022 · Biology definition): The biosphere is the part of the earth where living things exist. It encompasses all living things living in the lithosphere, atmosphere, and hydrosphere.
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.
The flow of energy and the cycling of nutrients through ecosystems, the regulation of populations, and the stability of biological communities, all of which support the continued maintenance of life, rely on the diversity of species, their adaptations to local physical conditions, and their coevolved relationships.
