Life exists only in the biosphere; organisms are found only in the thin outer layer of the Earth's crust, and are always separated from the surrounding inert matter by a clear and firm boundary. Living organisms have never been produced by inert matter. In its life, its death, and its ...
Nontrivial interaction of biotic and abiotic components is considered as a driving force of biosphere's progress and a guarantee of its stability. Biogeochemical cycling is interpreted as a stage of the general process of matter self-organization, as a manifestation of principle of maximization of ...

In the biosphere, human interference does not often directly change species diversity but increases the probability of transmission of pathogens by affecting species composition and community vulnerabilities. “This is not simply an ecological environment problem,” commented Wang Huo, deputy secretary-...
20% is absorbed by the atmosphere. 50% is absorbed by ground, water and vegetation. Less than 1% of the absorbed energy is used inphotosynthesis. This small percentage is the energy base for all life on the biosphere. HOW PHOTOSYNTHESIS CAPTURES ENERGY Photosynthesisconverts radiant energy into...
The response of atmospheric chemistry on earthlike planets around F, G and K Stars to small variations in orbital distance One of the prime goals of future investigations of extrasolar planets is to search for life as we know it. The Earth's biosphere is adapted to current cond... JL Grenf...
The purpose of this chapter is to explore cross-system patterns in Dissolved Organic Matter (DOM), bioavailability with data obtained from in vitro bioassays. The key components in the cycling of organic matter in the biosphere: its production, transformation, and degradation. In aquatic ecosystems...
In the nascent solar system, primitive organic matter was a major contributor of volatile elements to planetary bodies, and could have played a key role in the development of the biosphere. However, the origin of primitive organics is poorly understood. Most scenarios advocate cold synthesis in th...

Minerals are widely assumed to protect organic matter (OM) from degradation in the environment, promoting the persistence of carbon in soil and sediments. In this Review, we describe the mechanisms and processes operating at the mineral–organic interface as they relate to OM transformation dynamics...
