Earth's biosphere is divided into several biomes, inhabited by fairly similar flora and fauna. On land, biomes are separated primarily by latitude. Terrestrial biomes lying within the Arctic and Antarctic Circles are relatively barren of plant and animal life. In contrast, most of the more populous biomes lie near the equator.

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 includes all life on our planet. Scientists study how biological processes, like photosynthesis, affect other parts of the Earth system. Humans are only a small fraction of Earth's biosphere, but our actions have a large impact.

2023年10月19日 · 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.

2023年3月6日 · 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.

2023年12月4日 · The biosphere of the Earth incorporates environmental factors such as suitable temperature, moisture content, nutrition and energy, and minerals that are crucial to sustaining the life of species. The biosphere is essential in producing organic material since the oxygen and nitrogen produced through oxygen synthesis are the molecules that ...

The great richness of adaptations found among different populations and species of living organisms is Earth’s greatest resource. It is a richness that has evolved over millions of years and is irreplaceable.

2022年8月17日 · Also referred to as the "Ecosphere," the biosphere is a relatively thin zone of the Earth's surface that supports life. The word "biosphere" was initially used in 1875 by the Austrian geologist Eduard Suess to refer to the region of the Earth where life can be found.

2024年12月18日 · NASA biosphere data are critical for understanding Earth's species diversity, climate regulation and change, and its ecosystem processes. Life within Earth’s biosphere consists of millions of species living in various types of biomes such as grassland, forest, desert, aquatic, and tundra areas.

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.
