Entropy increases from one level to another. Thus, the true statement about entropy is Option A.
Entropy is defined as the inability to perform a mechanical function. As the trophic level rises, it often loses a lot of energy, which is likely to cause Entropy.
Entropy is a measure of system uncontrollability. As the trophic level goes to another, energy is lost so further disruption occurs which increases the entropy.
Thus, Option A is the correct statement.
