Explain the idea that life relies on death

The idea that life relies on death is true because living things can be formed from the things which remains after the death of organisms by dead body. By dead bodies remaining material, we make many items for our survival. The other point is that the death is necessary because if the death rate will become less and birth rate will be increased then there will be shortage of needs which are essential for our survival.

carbohydrates: (starches and sugars) composed of carbon, hydrogen, and oxygen.

lipids: (fats, oils, and waxes) are made of carbon and hydrogen atoms.

nucleic acids: contain hydrogen, oxygen, nitrogen, carbon, and phosphorus. they are polymers of nucleotides. a nucleotide has three parts, a 5-carbon sugar, a phosphate     (-po⬇️4) group, and a nitrogenous base.

proteins: made up of nitrogen, carbon, hydrogen, and oxygen. they are polymers of amino acids.
