Cycles in Biology Cycles in biology play a fundamental role in the world that we live in. Cycles occur all around and inside of us in many different forms‚ from the Krebs to the Calvin cycle. There are large scale cycles happening and they are essential in regulating the nutrients and substances that are around us which without‚ life on earth could no function. One of the largest cycles that occurs all around us is in everyday life is the carbon cycle. The current atmospheric

THE ROCK CYCLE ● ● ● ● There are three main types of rocks: igneous‚ sedimentary‚ and metamorphic. Each of these types of rocks are formed in different ways and each type of rock can be changed into the other types of rock. This process is called the Rock Cycle. The rock cycle is the process that makes and recycles rocks. IGNEOUS ROCKS ● ● ● ● ● ● Igneous rocks are formed from magma. Magma cools and solidifies into rock. When igneous rocks are exposed on the surface‚ time and weather break the

4 Biogeochemical Cycles Project Due: Wed‚ Dec 12th/Thurs‚ Dec 13th Using your book‚ notes‚ & other creditable sources‚ you will produce a labeled diagram and summary of each of the 4 biogeochemical cycles showing the transfers and transformations of these vital substances. Make sure you address the specifics listed for each cycle. 1. Hydrological cycle On the cycle diagram label the following: a. condensation b. precipitation c. percolation/infiltration

ASSIGNMENT 1 Introduction In macroeconomics‚ business cycle played an important role to show what a national economy is going; therefore‚ this essay will define what business cycle is and its characteristics. Besides‚ all of variables such as Real Gross Domestic Product (RGDP)‚ inflation and unemployment rate and their behaviour in the business cycle will be also demonstrated in the second part. The final part of this essay will analyse and compare the situation of Australian economy and USA

I will start by describing the carbon cycle and how elements of my lifestyle impact the cycle. Photosynthesis converts the Carbon dioxide gas that exists in the atmosphere and in dissolved water to organic carbon. Organic carbon is brought back into carbon dioxide gas by a process called respiration. There are sources of organic carbon underground in the form of fossil fuels‚ human emissions and volcanic activity brings the stored carbon back into the cycle. As a human being who feed‚ move‚ breath

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

------------------------------------------------- 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

A cycle is a biological pathway or process in which the end product of one cycle becomes the starting point for the next cycles Write an essay about cycles. Respiration Cells in the body use ATP as a direct source of energy. The conversion of glucose into ATP takes place during respiration. There are 2 different types of respiration‚ the more common and frequent one is aerobic respiration which is the production of ATP for energy. The less common one is anaerobic respiration‚ the production
