Answer:
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.
It is the variable being controlled/changed to see if there are any effects on the dependent variable (the thing getting tested/measured)
