flow of energy through living systems

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. ..
