Only 10 percent of the energy stored in an organism can be passed on to the next trophic level. of the remaining energy, some is used for the organisms life processes and the rest is ...

the rest is eliminated as heat.

Explanation:

We can see that energy is passed to each organism in the food chain in a unidirectional way, always following the producer → decomposer direction. It is important to note that less energy is spent at each trophic level. Normally, only 5% to 10% of energy is passed to the next trophic level, and this phenomenon is called ecological efficiency. Given this low amount of transferable energy, a food chain hardly has more than five trophic levels. Most of the energy stored by the body at a trophic level is used in the body's metabolic processes, in addition, a part of the energy is eliminated in the form of heat.

The rest is eliminated as heat.
