Microbial processes in the nitrogen cycle The nitrogen cycle is a crucial process in the environment, as it involves the transformation and circulation of nitrogen in various forms. Microbial processes play a significant role in the nitrogen cycle, as they are responsible for carrying out key ...
The global nitrogen cycle is often referred to as the "nitrogen cycles," because the overall process is the result of the interactions of various biological and abiotic processes. Each of these processes can be considered as a self-contained cycle. This chapter presents an overview of several ...
Which process returns nitrogen gas to the atmosphere? a.nitrification b.denitrification Human alteration of the N cycle and its environmental consequences Early in the 20thcentury, a German scientist namedFritz Haberfigured out how to short-circuit the nitrogen cycle by fixing nitrogen chemically at ...
nitrogen cycle- the circulation of nitrogen; nitrates from the soil are absorbed by plants which are eaten by animals that die and decay returning the nitrogen back to the soil biological process,organic process- a process occurring in living organisms ...
Lovelock contends that this process is part of global climatic-control system. According to Lovelock, Earth acts like a super organism, with all its biological and physical systems cooperating to keep it healthy. He hypothesized that warmer conditions increase algal activity and DMS output, ...
The basic premise of discovering the fundamental laws and mechanisms governing the process of the evolution of the solar system is the discovery of the basic cause and the essential nature of the gravitational interaction between the Sun and planets. Both Newton’s law of universal gravitation and...
Denitrification is the most studied nitrogen cycling process in groundwater to-date, due to its importance for nitrogen pollution removal [5], although operation of the truncated pathway produces less desirable forms of inorganic nitrogen - NO2-due to its toxicity [24], and greenhouse gases NO ...
The nitrogen cycle is the process through which nitrogen in the atmosphere is converted into a form that can be used by both...
Regeneration of the coked catalyst is an important process of fluid catalytic cracking (FCC) in petroleum refining, however, this process will emit environmentally harmful gases such as nitrogen and carbon oxides. Transformation of N and C containing compounds in industrial FCC coke under thermal deco...
of grassland to cropland); CH4emissions from animals and excreta; N2O emissions from animal excreta, manure and mineral fertilizer applications; and atmospheric nitrogen deposition (Fig.1). We use the spatially explicit, process-based ecosystem model ORCHIDEE-GM, which includes parameterizations of ...
