The carbon cycle in life and biology...the story of creation

Living bodies are composed of chemical compounds
Its basic element is carbon, which is coal. Starch, sugar, fats, and proteins contain carbon as an essential element in composing their molecules. The synthesis of these compounds, as we mentioned and repeated, begins in the plant leaves by combining carbon dioxide with water in the presence of green dye and sunlight.
The animal dies, the plant dies, and how quickly small living organisms take over their corpses, most of them like bacteria and fungi, which are organisms of decomposition and putrefaction, and by demolition they destroy their complex organic compounds, transforming them into simple compounds with little chemical activity, such as those with which synthesis began in paper. Trees. So the carbon in these compounds has turned into carbon dioxide. This goes back to the atmosphere, or it goes back to the ground’s water, and both
A reservoir from which the plant derives its need for carbon to begin the process of creation.

But, also before death, living beings do not cease
It returns to this greatest storehouse, of the air, atmosphere, and water of the earth, something of what it took from it when it was first created. They are the secretions that these organisms secrete as they carry out life, such as urine, feces, and so on. The organisms of decomposition and putrefaction dissolve them and return them to carbon dioxide again.

When breathing, a person burns his food in the cells of his body, and as a result of this combustion comes carbon dioxide, which goes out directly into the air, providing him with this essential compound in the process of creation.

Humans are not the only ones who breathe. Animals breathe, and plants breathe. It's the unit that
All the living things of the earth were gathered in one breath.

Nitrogen cycle

Although the carbon element is inherent in starches (and sugars), fats, and proteins, the plant cannot produce protein unless it has absorbed nitrogen from the earth, rather nitrogen salt. This means that nitrogen, along with carbon (and, of course, along with oxygen and hydrogen, which are the elements of water) is a genuine protein element.
Nitrogen and nitrogen are the same thing.

The nitrogen cycle is like the carbon cycle. What we said about the carbon cycle involves death, organisms rotting and decomposing simple nitrogen compounds that flow with the water of the earth until they reach the roots of plants and absorb them.
While living organisms secrete organic materials other than what we mentioned, they undergo what happens to the materials of corpses after death, in terms of decay, simplifying their composition, and returning them to their original sources, to air and earth.
