Re: What is death?

Death is the end of life for a vessel made of cell(s). That vessel may be me or you, or a cat, dog, aphid, rose, cactus, bacteria, or virus etc. Heart activity controls oxygen flow but plants and virus don't have hearts. Brain activity controls the non-autonomous functions that support life but as near as we can tell neither an apple nor a potato have a brain. So whatever life and death are they do not require a brain nor a heart.
For mammals among other living creature the brain and the heart work together to send oxygen and nutrients to every cell in your vessel. In a plant, photosynthesis and chemical processes and some internal variation of veins and arteries move nutrients around. An apple falls from the tree and metaphorically its brain and heart have stopped. It is still alive though. Just like you or I would be with no brain and no heart activity.
As nutrients, water, oxygen, or other molecules stop arriving at the cells that need those types of molecules the individual cells begin to die off. The more cells that die off the closer the vessel is to being dead. Your heart and brain could cease and until enough cells die off you may still be resuscitated. Too many brain cells die off and even resuscitation won't return you back to your normal self. As time goes on the cells that make up the apple die off and the apple rots just like your corpse would in the ground or any food you leave in the fridge too long.
So How's about this for a concept. Life dies at different rates. Some life like a cell or bacteria could die almost instantly but the life energy in something like an apple fallen from a tree may take longer to dissipate than the life energy of a decomposing raccoon on the side of the road. But 1, 2, or 3 weeks will all produce similar types of effects on that apple and raccoon. Cells will die.
We have found that colder temperatures slow the process and warmer temperatures speed up the process. And we have also found that the less number of live cells in something the less appetizing it is as well as the less number of beneficial nutrients that we would get from ingesting this vessel of cells. Rotten food is rotten for a reason whether it is meat, dairy, fruit, or vegetable, the more life energy left in what we eat, the better it tastes and the healthier it is for us.
So life is the process of ingesting other life or simulating the ingesting of life by transferring another form of energy into nutrients. Plant live through water and sun. Some need more sun, others more water. When your vessel can no longer ingest life energy it can no longer produce life energy and the cells that make up your vessel will perish one by one then two by two. What happens after this we can only speculate.
