This document presents information about biogeochemical cycles including the water cycle, carbon cycle, oxygen cycle, nitrogen cycle, phosphorus cycle and sulfur cycle. It defines biogeochemical cycles as the circulation of nutrients through life and earth repeatedly. The main components of the water cycle are evaporation, transpiration, precipitation, infiltration, interception and runoff.

BIOGEOCHEMICAL CYCLES

6. Biogeochemical Cycle
The circulation of nutrients through life (bio) and
through earth (geo) repeatedly (cycle) is a
biogeochemical cycle.
In the other words, the cyclic exchange of nutrient
materials between living organisms and their non-
living environment is called biogeochemical cycle.
The biogeochemical cycles conserve the limited source
of raw material in the environment.

7. BIOGEOCHEMICAL CYCLES INCLUDES
1. Hydrologic cycle or water cycle
2. Gaseous cycle
 Carbon cycle
 Oxygen cycle
 Nitrogen cycle
3. Sedimentary cycle
 Sulphur cycle
 Phosphorous cycle

8. HYDROLOGICCYCLE
Hydrologic cycle is the process of transfer of moisture from
the atmosphere to the earth in the form of precipitation,
conveyance of the precipitated water by streams and rivers
to ocean and lakes etc, and evaporation of water back to
the atmosphere.
The main components of Hydrological cycle are-
1. Evaporation 4. Infiltration
2. Transpiration 5. Interception
3. Precipitation 6. Runoff
