Correct Answer: C
Solution :
Law of entropy states when a living or non living system is left to itself, then it tends to increase its disorder or randomness i.e. entropy. So entropy is the degree of unavailable or useless energy. Living systems carry a number of chemical reactions and physical changes. Since no energy transfer or transformation is cent percent efficient, there is a regular loss of energy, thus bringing entropy. Living systems overcome entropy by continuous input of usable or free energy. The living organism obtain this required free energy either form radiant energy by photosynthesis (eg. plants) or from ready made food (eg. animals).
