Want this question answered?
As energy and matter flow through an ecosystem, matter must be recycled and reused. Substances such as water, carbon, nitrogen, calcium, and phosphorus each pass between the living and nonliving worlds through biogeochemical cycles.
combustion (burning of fossil fuels) and decomposition.
carbon cycle
Primarily carbon (atomic number 6), but there are some nuclear processes that yield nitrogen (7) and oxygen (8).
Imines are those compounds in which nitrogen is attached to a carbon through double bond and to hydrogen through single bond, R-CH=N-H, carbon and nitrogen both are sp2 hybridized, they behave just like unsaturated hydrocarbons
There are many elements that cycle through the environment, but the ones you are probably asking about would be Carbon, Oxygen, and Nitrogen.

Oxygen and Carbon Dioxide
Water carries nitrogen and carbon through the environment.
combustion (burning of fossil fuels) and decomposition.
Some forms of nitrogen and carbon are carried through the environment by plants and animals.
the death of plants and animals release nitrogen and carbon dioxide gases
Oxygen, energy, and reproduction.
The carbon and oxygen cycle are related by complementary relationship. For example whenever animals and humans breath they breath in oxygen and breath out carbon. Another example is plant and trees tack in carbon for nutrients and releases oxygen.
carbon cycle
organic compounds such as carbon, hydrogen, oxygen, nitrogen etc are very important to all life
Through the biogeochemical cycle.
