Answer:
The correct option is<em> b. at each step, energy is lost from the system</em>
Explanation:
The amount of energy that travels from one trophic level to another is known to declines at each level. Infact, only 10% of the energy travels from one trophic level to another.
This is because most of the energy is lost by the organisms at each trophic level. It is due to the metabolic processes which occur in the organisms of each trophic level and most of the energy is lost as heat.
