A component of certain biological molecules like phospholipids, DNA and adenosine triphosphate (ATP), phosphorus is circulated in the environment through the soil, water rocks and living organisms.

Photosynthesis in plants takes care of the production of most of the oxygen.

Nitrogen is an essential component of biological molecules like amino and nucleic acids, but most living organisms cannot use the element in its pure form and need a derivative component, NH3(ammonia) to be able to synthesize organic components.

1. Removal of CO2 from the atmosphere by plants and bacteria.
2. Generation of organic molecules, and building of biological mass in plants.
3. Consumption of plants by animals.
4. Respiration of animals restoring the CO2 in the atmosphere.
5. Dead and decaying organic ...

• Carbon is the backbone element of all organic polymers, and we are ourselves known to be carbon-based life forms.
• The movement of CO2 and other carbon compounds through biological components is known as the fast carbon cycle.
• The abiotic components like rocks, soil and oc...

The planet’s ecosystem has many cycles, like the water cycle or the seasonal cycle, and one of the most important ones is the nutrient cycle. This is a biogeochemical cycle involving both living and nonliving components, describing the use, movement, and recycling of nutrients in the envi...
