Question

Which of the following statements about entropy is true?
a.
Entropy increases going from one trophic level to another.
b.
Increases in entropy lead to reversible processes.
c.
A system’s work output is limited when changes in entropy do not occur.
d.
All of the above


Please select the best answer from the choices provided

A
B
C
D

Answer 1

A

Explanation:
- (a) True: energy transfers between trophic levels are inefficient and produce waste heat, increasing entropy.
- (b) False: increases in entropy indicate irreversible processes; reversible processes have no net entropy production.
- (c) False: if entropy does not change (ΔS = 0) the process is reversible and can deliver the maximum possible work, not a reduced amount.
