biosphere

Examples of biosphere in the following topics:

• Mars and a Biosphere

  • A biosphere is typically defined as the part of the Earth and its atmosphere capable of supporting life.
  • A biosphere can also be thought of as an global ecological system that incorporates all living beings and their relationships with the lithosphere, hydrosphere, and atmosphere.
  • Currently, a great deal of research is going into developing hypotheses on a Martian biosphere.

• The Carbon Cycle

  • Carbon dioxide leaves the atmosphere through photosynthesis, thus entering the terrestrial and marine biospheres.
  • Terrestrial Biosphere: The terrestrial biosphere includes the organic carbon in all land-living organisms, both alive and dead, as well as carbon stored in soils.
  • Marine Biosphere: The carbon cycle in the marine biosphere is very similar to that in the terrestrial ecosystem.
  • The carbon cycle describes the flow of carbon between the atmosphere, the biosphere, and the geosphere.
  • Outline the flow of carbon through the biosphere and abiotic matter on earth

• Levels of Organization of Living Things

  • The biological levels of organization range from a single organelle all the way up to the biosphere in a highly structured hierarchy.
  • At the highest level of organization, the biosphere is the collection of all ecosystems, and it represents the zones of life on earth.
  • Taken together, all of these levels comprise the biological levels of organization, which range from organelles to the biosphere .
  • From a single organelle to the entire biosphere, living organisms are parts of a highly structured hierarchy.

• Biogeochemical Cycles

  • The elemental components of organic matter are cycled through the biosphere in an interconnected process called the biogeochemical cycle.
  • Thus, mineral nutrients are cycled, either rapidly or slowly, through the entire biosphere, from one living organism to another, and between the biotic and abiotic world.

• Sources and Sinks of Essential Elements

  • The element carbon moves from the biosphere to the geosphere and the hydrosphere.

• Overview of Bacterial Viruses

  • Bacteriophages are viruses that infect bacteria and are among the most common and diverse entities in the biosphere.
  • They are among the most common and diverse entities in the biosphere.
  • However, other phages occur abundantly in the biosphere, with different virions, genomes and lifestyles.

• Ocean Floor

  • Microorganisms, by their omnipresence, impact the entire biosphere.
  • For example, nitrogen which makes up 78% of the planet's atmosphere is "indigestible" for most organisms, and the flow of nitrogen into the biosphere depends on a microbial process called fixation.

• Microbes and Ecosystem Niches

  • Microbes live in all parts of the biosphere where there is liquid water, including soil, hot springs, the ocean floor, acid lakes, deserts, geysers, rocks, and even the mammalian gut.
  • By virtue of their omnipresence, microbes impact the entire biosphere; indeed, microbial metabolic processes (including nitrogen fixation, methane metabolism, and sulfur metabolism) collectively control global biogeochemical cycling.

• Microbial Environments and Microenvironments

  • They live and thrive in all parts of the biosphere where there is liquid water, including hostile environments such as the poles, deserts, geysers, rocks, and the deep sea.

• Electron Donors and Acceptors

  • In the present day biosphere, the most common electron donors are organic molecules.
  • Because of their volume of distribution, lithotrophs may actually out number organotrophs and phototrophs in our biosphere.
