The law of thermodynamics states that not all energy is used because . A.) first; some of the energy disperses as heat b.)second; some of the energy is destroyed c.)first; some of the energy is destroyed second; d.)some of the energy disperses as heat

second)some of the energy disperses as heat

Explanation:

This  second law of thermodynamics  states that in the course of conversion  of energy from  one form  to another in an organisms,this can not be 100% efficient ( there is constant increase in entropy of the systems in the organism)as some of  the  energy is dissipated as heat in the course of conversion.

Thus in  a food chain as energy is been converted from one trophic level( primary consumer) to another( secondary consumer) these organism makes use of the energy to do biologic work.Therefore as this is passed to other organism in the tropic levels not all the  initial energy will be available ,as some has been lost during biology work,respiration , excretion ,movements and locomotion. in the subsequent organisms.

Thus the entropy of the organisms involved increases as energy is been transmitted from one trophic level to another which leads to heat dispassion.
