b) Energy cannot be transferred or transformed.

c) Also called The Principle of Creation of Energy.

d) Energy can be destroyed.

Practice: Which of the following images has less entropy?

b) Image B has less entropy.

Concept #3: Second Law of Thermodynamics

Practice: When chemical, transport, or mechanical work is done by an organism, what happens to the heat generated?

a) It is used to power yet more cellular work in the surroundings.

b) It is captured to store energy as more heat in the system.

c) It is used to generate ADP.

d) It is lost to the environment.

Practice: Which of the following statements is true regarding how energy moves up the food chain?

a) All of the energy is not transferred from producer to consumer because some of the energy is destroyed.

b) All of the energy is transfer from producer to consumer.

c) All of the energy is not transferred from producer to consume because some of the energy is lost as heat.

d) None of the above.
