Carbon Cycle (With Diagram) | Ecology

As carbon is the basic element of life, the carbon cycle is a very important biogeochemical cycle at the global level. This carbon cycle is characterised by a very active atmospheric reservoir pool that has been valuable to human interference, which, in turn, has changed the weather and climate in ways that has affected life on earth. In the latter [...]

Nitrogen Cycle (With Diagram) | Ecology

All molecules of biological importance, except water, carbohydrates and fats, contain nitrogen. Proteins, amino acids, chlorophyll etc. all contain nitrogen. Of total body dry weight, nitrogen makes up almost 13%, which is the third-most abundant element after carbon (48%) and oxygen (24%). The atmosphere contains approximately 78 per-cent nitrogen, mostly in gaseous form (N2), and thus forms the greatest reservoir [...]
