The correct response is:

because energy is lost to the environment as heat between levels.

In ecological terms, when energy is transferred from one trophic level to the next, much of it is lost primarily as heat due to metabolic processes, leading to the general rule of thumb that only about 10% of the energy is passed on to the next level.

I apologize for any confusion. The correct answer to why only about 10% of energy is transferred from one trophic level to the next is:

because energy is used for metabolism at each level.

Metabolism at each trophic level involves processes that require energy, and as a result, a significant portion of the energy consumed is used for growth, reproduction, and other metabolic activities. Additionally, some energy is lost as heat, which aligns with the concept of energy loss. Thank you for your patience, and please let me know if you have any other questions!
