there are all types of chemicals in the biosphere. like, for example, smoke from nuclear factories and pollutants in the air
Here are two Glucose is C6H12O6. Carbon dioxide is CO2
oxygen
Oxygen is released into the biosphere by plants during photosynthesis. It is not entirely lost for the oxygen is used by humans for breathing.
There is no chemical formula for zinc, it is an element. It is represented by the symbol Zn.
Silver is already ametallic chemical element. But so is mercury (chemical element), and it can supposedly be turned into gold, which is another chemical element.
A chemical element is homogeneous only if it is monoisotopic; but in practice this aspect is neglected. A chemical element is not a "change".
An atom is the smallest particle of an element that still has the chemical characteristics of that element
Biogeochemical cycling.

matter, chemical raw materials
Biogeochemical cycling is the continuous cycling of chemical elements. This is through the biotic and abiotic components of the biosphere.

Phosphorus
There is no chemical formula for zinc, it is an element. It is represented by the symbol Zn.
This chemical element is nickel.
Biogeochemical cycling is the continuous cycling of chemical elements. This is through the biotic and abiotic components of the biosphere.
Nitrogen is lost in the biosphere. Biochemical processes help the Earth rebuild the nitrogen lost. Exchanges of nitrogen are slow and steady.
biochemical cycles connect biological, geological, and chemical aspects of the biosphere.
