A nutrient cycle (or ecological recycling) is the movement and exchange of organic and inorganic matter back into the production of living matter. The process is regulated by food web pathways that decompose matter into mineral nutrients. Nutrient cycles occur within ecosystems. Ecosystems are interconnected systems where matter and energy flows and is exchanged as organisms feed‚ digest‚ and migrate about. Minerals and nutrients accumulate in varied densities and uneven configurations across the

Charles Parker Investigation 6: The Copper Cycle CHEM 101 Lab-M/630 As an investigation of the copper cycle lab group 6 conducted an experiment on 6 October 2014 at Arizona State University laboratory that would demonstrate the cycle of reactions that copper (Cu) can produce when introduced to with other substances/reactant. The purpose of the investigation was to notice the transformation of a specific quantity of copper wire (g) as it undergoes its coordination reactions until a reduction method

Nitrogen cycle Nitrogen gas is a colourless‚ odourless and non-toxic gas which makes up about 78 percent of the atmosphere. Nitrogen is extremely important to living material; in fact plants‚ animals and humans could not live without it. Sprent (1987) argued that nitrogen cycle is the most important process to living organisms after the carbon cycle. But nitrogen exists as dinitrogen (N2) in the atmosphere‚ which living things‚ particularly plants‚ cannot synthesize (citation) The process of nitrogen

CHAPTER 12- THE CELL CYCLE I. Concept 12.1- Cell division results in genetically identical daughter cells A. Overview 1) The continuity of life is based on the reproduction of cells or cell division. 2) The cell division process is an integral part of the cell cycle‚ the life of a cell from the time it is first formed from a dividing parent cell until its own division into two cells. B. Cellular Organization of the Genetic Material 1) A cell’s endowment of DNA‚ its genetic

Topic 9 - The Carbon Cycle Aspects of the carbon cycle are similar to the hydrologic cycle because both are good examples of “Interactions between the systems". Textbook – topic not covered in text. http://www.windows2universe.org/earth/ The Carbon Cycle Neglecting the small amount of carbon (C) added to Earth by meteorite impacts‚ there is a fixed amount of carbon on Earth (~800‚000 billion tonnes). All living things are made of carbon but carbon is also a part of the ocean‚ air‚ and

------------------------------------------------- The Processes of the nitrogen cycle Nitrogen fixation Atmospheric nitrogen must be processed‚ or "fixed" (see page on nitrogen fixation)‚ in order to be used by plants. Some fixation occurs in lightning strikes‚ but most fixation is done by free-living or symbiotic bacteria. These bacteria have the nitrogenase enzyme that combines gaseous nitrogen with hydrogen to produce ammonia‚ which is then further converted by the bacteria to make their own organic
