Entropy increases from one trophic level to another because a)the available energy from one trophic level to another increases b)energy is lost as heat energy, increasing randomization c)the amount of biomass decreases d)all of the above

Option (B)

Explanation:

The entropy is often defined as the measure of the thermal energy of a particular system per unit temperature, as a result of which energy is insufficient to do any work. It is directly related to the temperature and loss of energy to heat. In simple words, it is referred to as the degree of randomness.

The entropy is directly proportional to the temperature and inversely proportional to the loss of energy. Due to this, there occurs an increase or decrease in entropy from one trophic level to another. Each trophic level organism performs several metabolic procedures in which huge amount of energy is lost into the environment which leads to the elevation in the entropy of any system.

Thus, the entropy increases from one trophic level to another because the energy is lost as heat energy, thereby increasing the randomization of the system.

hence, the correct answer is option (B).
