Question

What law accounts for the decrease of energy at each trophic level?

Answer 1

Second law of thermodynamics

Step-by-step explanation:

The second law of thermodynamics states that whenever energy is transformed, there is a loss energy through the release of heat. This occurs when energy is transferred between trophic levels as illustrated in a food web. When one animal feeds off another, there is a loss of heat (energy) in the process.
