The Journal of Ecosystem & Ecoraphy aims to publish quality review articles in all fields pertaining to development and understanding of ecosystems. Biogeochemical cycles are intrinsic part of an ecosystem. The transfer of chemicals, nutrients and energy from one trophic level to another is facilitated by biogeochemical cycles. The important cycles are: carbon cycle, nitrogen cycle, phosphorous cycle, sulphur cycle, water cycle and rock cycle. Nitrogen cycles consists of different processes: nitrogen fixation, assimilation, ammonification, nitrification, denitrification, anaerobic ammonium oxidation and few other processes. Nitrogen in any organism can be traced back to soil in the case of plants, plants in the case of herbivores, herbivores through plants in the case of carnivores and detritivores from either plants or animals. The carbon cycle has different exchange pathways between: the atmosphere, the terrestrial biosphere, the oceans, the sediments and the earth's interior. In the recent years, due to population explosion and due to over exploitation of natural resources above their renewable capacity, there occurred an imbalance in the ecosystem which called for an important intervention; Ecosystem Management. The conservation of ecosystem diversity and its natural resources in an effort to longer sustainability is called Ecosystem Management. It is also an effort to sustain human livelihood along with its stability.
