if energy is neither created nor destoyed then if a human dead where his/her energy goes reply

Answer:
After our deaths, the energy contained in us simply disperses into the surrounding environment. As our bodies (or giblets) cool, the excess heat energy we possess in life is distributed to the surrounding air, liquid, or objects our bodies are in contact with. Furthermore, the energy contained in the compounds in our bodies (sugar, fat, protein, almost everything) disperses as well. The bacteria and other organisms that decompose us absorb some of it, and much of it is lost too as heat to our surroundings as the chemicals break apart (either when eaten by decomposers or naturally) into smaller, lesser-energy forms.
In summary, after the death of the human body (or any other, for that matter) the energy in it is dispersed to its surroundings, either in the same form or a different one, becoming one with the energy already in the surroundings and dissolving into it, ready to be absorbed by another living, growing organism. :)
Explanation:
Sunlight is about 47% light and 47 % infra red that produces heating and 6 % ultraviolet (harmful). Photosynthesis turns sunlight into food. The infrared keeps the atmosphere warm for us delicate human beings. We know the photosynthesis process, called the Kreb’s cycle, but we cannot duplicate it to make our own food. So we still have to rely on plants to do that function.
We are 43 % human and the rest of us, mainly lining the digestion tract and gut, consists of bacteria, viruses, fungi etc. They perform the vital task, which we cannot do on our own, of digesting the food and extracting the sun’s energy from it. Some of this food and energy goes into making new proteins to replace the worn out proteins in our bodies. Some we use to do useful work as in walking, cooking, gym, pushing a pen, tapping a keyboard, reading or thinking which pushes neurotransmitters around between our brain cells etc. Much of the food gets burned up in our cells to produce body warmth. This energy is degraded in the process and appears as heat energy which cannot be collected and used to do useful work.
The energy input of a person is due to the food that has miraculously trapped the sun’s energy. That is balanced by an output of useful work when we focus our energy on some task plus an output of body heat energy that seldom does any useful work as the energy radiates out in all directions instead of being focused in one direction. Energy input equals energy output. The total energy transfer is a zero sum.
Energy input from the food is useful energy. Energy output is partly useful work done and partly degraded energy that does nothing useful.
So some of the useful energy input is wasted by us humans. Thus we are inefficient energy users. And so the sun keeps pumping in excess energy to keep us inefficient energy gobbling humans going.
Thus the final end of the sun’s energy is to appear as warmth in our atmosphere as our body temperature pumps out heat energy day and night. Some of this body-warmth energy adds to the heat energy content of the atmosphere. Some is reflected out to the cold of space. Some gets absorbed by plants to help their cycle.
When a person dies they stop absorbing food energy and also stop giving out energy as body warmth and any work that they did. So there is still a zero sum energy transfer. Zero energy absorbed equals zero energy given out. So only in death is the energy equation efficient.

not satisfied, reply how can't we use the reverse process to gain energy to the dead body
