All living organisms eventually die because cells are progressively worn down by free radicals. Free radicals, or reactive oxygen species, are produced as side products from the biochemical reactions of cell metabolism. They are unstable molecules that will react with, and thereby damage, almost anything they come into contact with, including DNA, cell membranes, and proteins.
Through evolution, organisms have developed mechanims to cope with free radicals and dispel their harmful effects. However, the detrimental effects of free radicals on cells eventually overcomes these coping mechanisms as the organism ages, eventually resulting in death.
You may ask why evolution hasn't taken a step further and developed a never ending mechanism to deal with the free radical problem. The answer lies in the properties of evolution itself. Selective pressures on species only acts on individuals at the reproductive stage of life. Natural selection of an individual that lives longer over an individual that doesn't live as long wouldn't take place as both are able to pass on their genes.

Why is it necessary for organisms to evolve?
If they do not evolve, they may eventually die out.
What is the difference between living cells that are organisms and living cells are not organisms?
Single celled organisms are examples of living cells that are organisms. Most other living cells are parts of living organisms, but could not survive long on their own.
What is the difference between bacteria and living organisms?
No difference. Bacteria are living organisms.
How do living organisms help soil?
Living organisms provide nutrients for the soil.
How do living organisms grow?
Living Organisms grow from cell division and growth hormones
Do animals die?
Yes, all living organisms eventually die.
Can horses die?
Yes horses can die, all living things, or organisms die eventually.
What will happen if all living organisms lose the capacity for reproduction?
Then all species of organisms will eventually die out.
What would happen if an organism's habitat disappeared?
The organisms living in the habitat will eventually perish(die).
What would boiling do to most living organisms?
It will most likely heat up to the extreme that eventually it will die.
What is generally accepted as the origin of living organisms?
Prebiotic chemical evolution gave rise to progressively more complex molecules and eventually to living organisms
Why do dalmatians have to die?
Because eventually every living being dies. Dalmatians, being living things, must eventually die.
Why is it necessary for organisms to evolve?
If they do not evolve, they may eventually die out.
Eventually how do all living things conclude their natural lifestyle?
All living things eventually die.
Can a living thing or organism survive without other living things?
Long term, no. All living things are a part of the biosphere and the great cycle this encompasses. Without the other organisms that form part of this cycle, a living thing would eventually die.
What happens to a population or organisms when limiting factors needed for the organisms to survive are not ideal?
the organisims will eventually die off after their source of nutrients is taken away- eventually if no reliable nutrients are avaible, ther organisms will eventually become extinct
Without the sun energyall living organisms will?
I think they will die...
