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. It ranges from heights of up to 12500 meters above sea level to depths of at least 8000 meters in the ocean.
Sep 16, 2024 · Human activities are causing major alterations to the patterns of energy flow and nutrient cycling through ecosystems, and these activities are eliminating populations and species that have not even been described but which might have been of central importance to the maintenance of ecosystems.
Sep 16, 2024 · The biosphere is the thin life-supporting stratum of Earth’s surface, extending from a few kilometres into the atmosphere to the deep-sea vents of the ocean. It is composed of living organisms and nonliving factors from which the organisms derive energy and nutrients.
- The biosphere supports all life on Earth, 3 to 30 million species of plants, animals, fungi, single-celled prokaryotes such as bacteria, and single...
- The two components of the biosphere are called the abiotic and the biotic. The abiotic, or nonliving, portion of each ecosystem includes the flow o...
- The major cycles that occur in the biosphere are the carbon cycle, nitrogen cycle, sulfur cycle, phosphorus cycle, and hydrological (water) cycle.

Oct 19, 2023 · The biosphere is made up of the parts of Earth where life exists—all ecosystems. The biosphere extends from the deepest root systems of trees, to the dark environments of ocean trenches, to lush rain forests, high mountaintops, and transition zones like this one, where ocean and terrestrial ecosystems meet.
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.
What is the Biosphere? The Biosphere includes all life on Earth including life living on the Earth's Geosphere and in Hydrosphere, including humans and all organic matter that has not yet decomposed. This important sphere distinguishes Earth from all other planets in our solar system as life evolved (and continues to evolve) since Earth's early ...
