Biogeochemical cycle, Biology

The cyclic exchange of nutrient material between organisms and non-living  environment is called biogeochemical  cycle ,'geo means earth: ''chemical' means chemical elements, thus biogeochemical cycle can be explained as cycle paths in which circulation of all essential elements takes place from the environment  to the organisms and back to the  environment  some important biogeochemical cycles  are as follows:

1.         Water  cycle or hydrological cycle

2.         Oxygen cycle

3.         Nitrogen cycle

4.         Carbon cycle

5.         Sulphur cycle

6.         Phosphorus cycle

The first are gaseous cycles as they circulate between land  and atmosphere where as the last one is sedimentary cycle it does not the atmosphere.
