Defining A Biosphere Britannica The biosphere is a global ecosystem composed of living organisms (biota) and the abiotic (nonliving) factors from which they derive energy and nutrients. (read e.o. wilson’s britannica essay on mass extinction.) before the coming of life, earth was a bleak place, a rocky globe with shallow seas and a thin band of gases—largely carbon. 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.
Biosphere Definition Resources Cycles Facts Britannica Biosphere ecosystems, biodiversity, life: the biosphere supports between 3 and 30 million species of plants, animals, fungi, single celled prokaryotes such as bacteria, and single celled eukaryotes such as protozoans (figure 1). of this total, only about 1.4 million species have been named so far, and fewer than 1 percent have been studied for their ecological relationships and their role in. Noun. a dip or depression in the surface of the land or ocean floor. biosphere. noun. part of the earth where life exists. biosphere reserve. noun. location recognized by the united nations as important to the relationship between people and the natural environment. carbon dioxide. The biosphere is that part of the earth where living things thrive and live. it is the portion of the planet that can sustain life. the earth has three other spheres: the atmosphere, the lithosphere, and the hydrosphere. however, not all of them are inhabited by living things. the portions or regions where organisms are found are collectively. The biosphere (which is technically a spherical shell) is virtually a closed system with regard to matter, [1] with minimal inputs and outputs. regarding energy, it is an open system, with photosynthesis capturing solar energy at a rate of around 100 terawatts. [2] by the most general biophysiological definition, the biosphere is the global.

The current biosphere meaning references all of life on earth in the lithosphere (the rocky crust of the earth), the atmosphere (air) and the hydrosphere (water). it includes all the ecosystems, biomes and organisms on the planet. the biosphere is a comparatively thin layer or zone of life that includes everything from bacteria to humans. 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. since the biosphere supports life on earth, it distinguishes our planet from other planets in the solar.
