Second law of thermodynamics

Consider the statement (A) and (B) and identify the carrect answers. A . First law of thermodynamics specifics the consitions under which a body can use its heat energy to produce the work. B. Second law of thermodynamics states that heat always flows from haot body to cold body the itself .

The second law of thermodynamic states that in a cyclic process,

What energy percentage can be captured by the organisms of next trophic level or transfer of energy from one trophic level is according to second law of thermodynamics. The efficiency of energy transfer from herbivorous to carnivorous is

When an object cools down, heat is withdrawn from it. Does the entrophy of the object decrease in this process? If yes, is it a violation of the second law of thermodynamics stated in terms of increased in entrophy?
