Energy that is not passed on from one trophic level to the next is _______.

A
lost as heat
B
returned to the sun
C
destroyed
D
all of the above
19

Why is a system’s work output limited?

A
Entropy decreases with each stage of a system, causing a decrease in available entropy to carry out each stage.
B
Systems tend to become less randomized over time, which causes spontaneous processes to no longer occur.
C
Energy is destroyed in each stage, causing the amount of available energy to decrease with each stage.
D
Energy is lost as heat in each stage, causing the amount of energy available to decrease with each stage.
