energy cycle in living systems

Energy can be defined as the ability to do work. A good source of energy would be the one which would: do a large amount of work per unit volume or mass be easily accessible be easy to store and transport and be economical Fossil Fuel Fossil fuel is a hydrocarbon de..

Summary - In the modern system of classification, living organisms are grouped under five kingdoms, as proposed by Whittaker (1966). The Kingdom Monera includes bacteria and blue green algae, both of which possess prokaryotic cells. Bacteria are unicellular prokaryotes that have..

Energy is a number that we associate with a system of one or more objects. If a force acts on one of the objects, making it move, then the number changes. After countless experiments, scientists and engineers realised that if the scheme by which we assign these energy..

If the state of a system at the end of a process is the same as the state of the system at the beginning, the process is called a Cyclic process . If all parts of a cyclic process are reversible, it is a reversible cycle..

' (bio - living organisms; geo - soil, rock, etc, chemicos - elements and their compounds). These materials have been used again and again in the formation of new generations of the organism. In other words, the matter is continuously recycled. By definition, "The movement or circulation ..

Phosphorus Cycle - Phosphorus is an essential nutrient to biological systems. Its requirement is mainly seen in nucleic acids, cell membrane, bones and tee..

Oxygen is another essential element for living organisms. It is present in large quantities (20.95% v/v) in the atmosphere and is also seen in bound state in water and as oxides and carbonates in rock..
