Answer:

The correct answer would be B. It is used for cell functions or transformed to heat energy.

It can be explained with the help of ten percent law which states that only ten percent of the energy available at a particular trophic level is transferred to the higher trophic level.

The rest or maximum of the energy is lost as heat as a result of cellular respiration.

It is why the tuna only gets 100 joules (ten percent of 1000) of energy from sardine.
