Answer:
The correct answer is A)
Some energy is transferred to the organisms, and the remaining energy is released into the ecosystem as thermal energy.
Step-by-step explanation:
As we move up the trophic levels in an ecosystem, we observe that the amount of energy keeps on reducing at each trophic level. This phenomenon occurs because not all energy is transferred from one trophic level to another is an ecosystem. Most of the energy is released as heat into the atmosphere. Almost, 10% of the energy is known to flow from one trophic level to another in an ecosystem.
