The Nitrogen Cycle Essay - 439 Words - StudyMode.
The Nitrogen Cycle Essay Sample. The element nitrogen is essential to living organisms. Nitrogen moves through the different ecosystems by the way of the nitrogen cycle. Plants and microorganisms assist nitrogen on its journey through the nitrogen cycle (Gruber and Galloway 2008, 293). In nature a limited number of bacteria species and blue-green algae have the ability to biologically fix.
The nitrogen cycle is the biogeochemical cycle by which nitrogen is converted into multiple chemical forms as it circulates among atmosphere, terrestrial, and marine ecosystems.The conversion of nitrogen can be carried out through both biological and physical processes. Important processes in the nitrogen cycle include fixation, ammonification, nitrification, and denitrification.
The illustration shows the nitrogen cycle. Nitrogen gas from the atmosphere is fixed into organic nitrogen by nitrogen-fixing bacteria. This organic nitrogen enters terrestrial food webs. It leaves the food webs as nitrogenous wastes in the soil. Ammonification of this nitrogenous waste by bacteria and fungi in the soil converts the organic nitrogen to ammonium ion—NH4 plus. Ammonium is.
Nitrogen cycle, circulation of nitrogen in various forms through nature. Nitrogen, a component of proteins and nucleic acids, is essential to life on Earth. Although 78 percent of the atmosphere is nitrogen gas, this gas is unusable by most organisms until it is made available by a series of microbial transformations.
Are you searching for details regarding the nitrogen cycle steps, that is, the cycle of life? The following BiologyWise article will cover all the details of the nitrogen cycle and introduce you to one of the most effective processes in nature. The nitrogen cycle is one of the most important nutrient cycles that takes place in the natural world. Nitrogen is the most important component for all.
Nitrogen cycle. Nitrogen is a critically important nutrient for organisms, being one of the most abundant elements in their tissues, and an integral component of many biochemicals, including amino acids, proteins, and nucleic acids. The availability of biologically useful forms of nitrogen is a common limiting factor in the productivity of plants. This is especially true of plants growing in.
Explanation of the Carbon Cycle. The Carbon cycle implies the exchange of Carbon between the various organic and inorganic elements in the atmosphere and the biosphere. The elements which release Carbon in the atmosphere are called the sources, while those that absorb Carbon from the atmosphere are called the sinks.
