If living things have energy, and energy can never be destroyed, then where does that energy go after we die?

Livings things have energy only because they aquire it from food. Using this energy they live, survive and do various tasks. When they die, what ever metabolic energy is left is used by the bacteria which decompose the body.

The conservation of energy rule in physics dictates that energy is always conserved, so it can't be destroyed merely changed to another type. Perhaps an example could be in a crash, the kinetic energy is turned into sound and heat energy primarily, but the energy still exists.

Conservation of energy and momentum basically means that energy is never created or destroyed, and same with momentum. It has to come with somewhere. If energy or momentum leaves one system, it must enter another system. If energy appears in a system, it had to have come from one. Momentum is never really gained or lost, and same with energy -- it is simply transfered from one body to another. An elastic collision is one in which no kinetic energy is lost, all of it is transfered directly from one system to another.. In an inelastic collision, some of the energy is transfered to a third system (via sound waves, heat energy, or other such energy loss). In this case of an inelastic collision, the total kinetic energy of the two bodies before, is not the same as it is afterwards. The difference in these values would be the energy "lost" from these systems that was tranfered elsewhere.

Living things interact with the energy and matter of a larger environment. Dead things do not. So, what you find is that often living things will eat and get energy from dead things. Dead things do not do this. They pretty much just rot. So, you can think of it as eaters and eaten.

The energy isn't destroyed, but it is reorganized into different forms.  Think of it this way: Imagine you have a bunch of fridge magnets with words on them, and you arrange them into a brilliant poem.  When you come back later, someone else has rearranged the magnets.  All of the magnets have been "conserved"-- they're still there, and they're just as magnetty as ever-- but the particular shape that they were in when they were your brilliant poem is unrecoverable.  Sorry. <3

All energy eventually ends up as heat.  It's a consequence of the second law of thermodynamics

In the words of Einstein, matter is simply a different manifestation of energy.\n\n\nAs for energy, from everything we know about thermodynamics, it cannot be created or destroyed. Energy didn't come from anywhere and can't go anywhere. It simply IS.\n\nWhy? Well, we're not sure yet.

Light only travels until it is absorbed, dissipated to other types of radiation (no longer referred to as "light"), or expended as some other form of energy.\n\nThis can mean "forever". Of course, that depends on various important factors of light which rely on concrete proof. At the moment, there are differing theories about how light works, why, and what it is.

There is a law in physics that states energy cannot be created or destroyed - it can only be changed.  Everything, including you is made of energy.\n\nThat's all I know for sure.  My gut tells me we have nothing to fear.

Matter is anything that occupies space. Matter is not alive so therefore cannot die.

Biomass is lumps of dead things.\nThe dead things were either plants or animals that ate plants (or animals that ate animals that ate plants).\n\nThe biomass could be burned to release heat and light.\nOr the biomass could be fermented to produce methane which could be burned to release heat and light.\nEither way, energy is available from biomass.\n\nIn the simplest case, say a plant being burned (logs for instance), from where did the plant get all that energy?

If you consider that matter and energy are two forms of the same thing (that's what the E=mc2 is about), then yes, this is never created or destroyed.  Some matter is converted to energy (e.g. nuclear burning in the core of stars), but it is never completely destroyed.  So yes, everything created is still here in some form or another.

the real question here is: Do we actually die at all?\n\nSure, the functions of the body stop working, but they almost immediately begin to serve new functions.  Mainly, in the beginning, the processes of the body begin to immediately breakdown the body casing.  Once the body is dissolved, is becomes food and nutrient, which in turn serves to produce life, on many different levels.  \n\nAs for the "soul" who knows if it even exists.  We do know that the body's cells are full of energy.  We are also taught that energy cannot be created of destroyed.  So, the energy merely moves along, we could infer.  Perhaps the energy energizes other living creatures, perhaps it spurs a violent collision of atoms and particles resulting in a chaotic tropical storm.  perhaps too it leaves the earth alltogether and enters another dimension of life, after-life, or after-death realm.  Hell, maybe it even retains it's consciousness.  \n\nThen again, maybe nothing happens.  Maybe it's like a dreamless sleep that you never wake up from.  If that's the case, would you ever know that were dead?

Law of conservation of Mass is exactly what prevents something being permenantly destroyed or created from nothing. You can't destroy Matter and you can't create Energy from nothing, Everything that exists has existed since the begining of the universe. It is possible to turn matter into energy, as shown when burning fossil fuels or making an atomic bomb

Yes, your body is of this Earth.  After you die, you will never need it again.  But you will be born into a brand new spirit body and that journey lasts forever.

Life proceeds on chemistry.  Consumption of carbon proteins (or photosynthesis in plants) leading to the production of ATP (adenosine triphosphate).  ATP, being the energy storage and transfer molecule in just about all living cells is truly the stuff of life.

TRUE\nFirst of all all living cells do not produce energy from glucose only,but also from fats and proteins(during starvation).\nAnd then,most of the energy released is lost as heat energy.The remaining energy is stored as ATP( which is like a 'battery').Just as a battery can be 'plugged on' to different objects to produce light(torch),sound(tape recorder),etc so also the ATP can also be used as and when required to provide energy for locomotion,to produce light(glow worm),electricity(ray fish) etc.
