energy 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..

Traces of metal is necessary for the human and animal system to function efficiently. Some of the important metals required are iron, copper, zinc, sodium and potassiu..

Energy is the capacity to do work. All living organisms require energy for carrying on their vital metabolic activities. The primary source of energy for living system is solar radiation. The radiant energy of sunlight cann..

Every organism has a tendency to increase its entropy, which is very much in accordance with the second law of thermodynamics. In order to maintain its organisation at the molecular, cellular and organismic levels, every organism is forced to obtain energy from its surroundings, so that ..

. After studying various food chains and energy transfers in different ecosystems, Lindemann in 1942 gave the generalization called "The 10 per cent law". It shows that about 90% of the energy is used up at each level and only 10% of it is transferred to the next trophic level. ..

. In this case, a positive amount of work has to be done against the attractive force to take the charge from a given location to infinity. Similarly, the potential energy of a system of three charges q 1 , q 2 , q 3 located at r 1 , r 2 , r 3 respectively can be calculated. Wor..

The present system of classification, recognises the living organisms under five kingdom..

Living Beings are Organised - Organisation refers to a kind of structure or system or situation where the smaller components become arranged into larger ones in a hierarchical order of complexity, to co-ordinate with one another in performing common functions or achieving common..

The non-living resources include the air, water, energy, minerals, etc. Soil is also a non-living resource. However, since it also contains the microbes and other living organisms, it is sometimes referred to as mixed resourc..
