The right answer is D.eliminated as heat

It takes energy (heat or work) to break a link. And the formation of a bond is a phenomenon that releases energy (and in general heat)

In an exothermic reaction, bonds are broken, but more is formed than broken. The overall effect is a release of energy (therefore heat). The heat released is equal to the internal energy variation of the system.

Only 10 percent of the energy that is stored in an organism can be passed to the next trophic level. Of the remaining energy, some is used for the life processes of the organism and the rest is eliminated as heat. Therefore, option (D) is correct.

Further Explanation:

Energy is important for the survival of the organisms living on Earth.The solar energy that enters the Earth is transformed into the chemical energy by the producers (plants) that are present at the first trophic level. This energy then flows through each trophic level and supports all the consumers that occupy different higher trophic levels. However, not all the energy which is produced flows through each of the trophic levels. There is an energy loss at each trophic level as it moves to trophic level above it. Only 10 percent of the energy at a trophic level moves to the next trophic level.

The loss of energy transfer from a trophic level to the trophic level present above it occurs mainly due to two factors. The first factor refers to the use of energy by animals, which they use for several processes like locomotion and maintenance. Thus, some of the remaining energy is used up by cellular process. Secondly, according to the second law of thermodynamics, no biochemical reaction is 100 percent efficient. This implies that some of the chemical energy is liberated by cellular respiration and this energy is converted into the heat. This loss of energy in the form of heat is not beneficial to most of the organisms.

Thus, most of the remaining 90 percent of the energy is lost as heat and some is used up in the cellular processes.
