The biotic, or living, portion includes three general categories of organisms based on their methods of acquiring energy: the primary producers, largely green plants; the consumers, which include all the animals; and the decomposers, which include the microorganisms that break down the remains of plants and animals into simpler components for recycling in the biosphere. Aquatic ecosystems are those involving marine environments and freshwater environments on the land. Biosphere Definition Biology – Overview. Word origin: bios- meaning life + sphere. Omissions?

Earth's environment includes the atmosphere, the hydrosphere, the lithosphere, and the biosphere. Stated another way, the abiotic, or nonliving, portion of each ecosystem in the biosphere includes the flow of energy, nutrients, water, and gases and the concentrations of organic and inorganic substances in the environment. The biosphere extends from the deepest root systems of trees, to the dark environment of ocean trenches, to lush rain forests and high mountaintops. Mexican Biodiversity - What is the Biosphere. Energy from the Sun relentlessly bombarded the surface of the primitive Earth, and in time—millions of years—chemical and physical actions produced the first evidence of life: formless, jellylike blobs that could collect energy from the environment and produce more of their own kind. n. 1. Wimsatt points out many other features that levels may have: For example, processes at higher levels tend to happen at slower rates than processes at lower levels, higher level properties are typically multiply realized by lower level properties, and higher-level causal relationships are dynamically autonomous in the sense of being largely independent of what happens at lower-levels.

The elements carbon, hydrogen, nitrogen, oxygen, phosphorus, and sulfur, when combined as proteins, lipids, carbohydrates, and nucleic acids, provide the building blocks, the fuel, and the direction for the creation of life. The biosphere is a global ecosystem composed of living organisms (biota) and the abiotic (nonliving) factors from which they derive energy and nutrients. A non-living factor that shapes an ecosystem. A community is a collection of species populations. It is the basic element of nature. The part of the earth with living organisms: Term. Total Cards. At this level, the form, physiology, behaviour, distribution and adptations in relation to the environmental conditions are studied. Other points include energy transformations and transfers within the biosphere and the cyclic flow of materials needed for life. See more.
