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 stage cycle Stage one is the beginning of the sleep cycle‚ and is a relatively light stage of sleep. Stage one can be considered a transition period between wakefulness and sleep. In Stage one‚ the brain produces high amplitude theta waves‚ which are very slow brain waves. This period of sleep lasts only a brief time (around 5-10 minutes). If you awaken someone during this stage‚ they might report that they weren’t really asleep. Stage two is the second stage of sleep and lasts for approximately

CYCLES IN BIOLOGY This essay will give examples of cycles in biology from different scales of magnification‚ ranging from molecular level to populations and ecosystems. Cycles are sequences of events which repeat themselves in the same order‚ one event leading to the next. There are many examples of these in Biology. Cycles can be seen even at a molecular level in the body. An example of this would include the passage of action potentials down neurones in the nervous system. When the cell membrane

The Business cycle will guide the businesses‚ industries‚ and companies to act in a specific way‚ depending in which of the 4 phases the business cycle is. Since business cycle could be on

The Calvin Cycle Plants use energy from the sun in tiny energy factories called chloroplasts. Using chlorophyll in the process of photosynthesis‚ they convert the sun’s energy into storable form in ordered sugar molecules such as glucose. In this way‚ carbon dioxide from the air and water from the soil in a more disordered state are combined to form the more ordered sugar molecules. Carbon dioxide is captured in a cycle of reactions known as the Calvin cycle or the Calvin-Benson cycle after its

The Calvin Cycle By: MJ Pineda The Calvin Cycle is basically a part of photosynthesis where plants take in carbon dioxide and uses ATP and NADPH to make sugars from the CO2 and water for the plant to use or for animals to eat. It does not require light‚ and is interestingly called the "dark cycle" 1. The first step of this cycle consists of A carbon atom from carbon dioxide molecule will enter the cycle and joins with a five carbon molecule that is present. 2. The six carbon molecule that

Production Cycle The production cycle is a set of business activities and data processing operations associated with the manufacturing of products. Louwers (2007) points out that “the production cycle is closely linked to the acquisition cycle in which goods and services are purchased and to the revenue cycle in which the inventory is sold (p. 328). As products cycle through the stages from raw goods all the way through finished goods‚ the production cycle is concerned with how to account for
