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.
May 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.
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.

All living organisms perform gas exchange to survive. Animals, including humans, take in oxygen gas from the atmosphere and breathe carbon dioxide back into the atmosphere. In contrast, plants use carbon dioxide to prepare food, releasing oxygen as a byproduct. In both cases, the biosphere interacts with the atmosphere. When plants draw water from ...
All biogeochemical cycles, such as carbon, nitrogen, phosphorous, and sulfur, work on the same principle of interaction between the biosphere and atmosphere. The minerals are removed from the atmosphere, used by living organisms, returned to the Earth, and recycled back into the atmosphere. The same is true for the water cycle, which determines how...
The green plants produce food consumed by herbivores, the primary producers. The herbivores are then consumed by carnivores (meat-eating animals like lions and tigers) and omnivores (plant- and meat-eating animals like humans). The apex consumers, like hawks, feed on dead organisms. The decomposers mineralize the organic remains of plants and anima...
Jun 11, 2019 · The biosphere is the layer of Earth that includes all living things. It is one step above ecosystems and includes organisms that live in communities of species or populations, which interact with each other.
A biome ( / ˈbaɪ.oʊm /) is a distinct geographical region with specific climate, vegetation, and animal life. It consists of a biological community that has formed in response to its physical environment and regional climate. [1] [2] Biomes may span more than one continent. A biome encompasses multiple ecosystems within its boundaries.
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.
