2. BIOGEOCHEMICAL CYCLE
The cyclical path of the elements from the abiotic
system to the biotic system and back.
Bio means living organism.
Geo means water, air, earth.

3. PHASES OF BIOGEOCYCLE CYCLE

4. BIOTIC PHASE
1. Flow of chemicals in the living organisms
through the food chain

5. ABIOTIC PHASE
The distribution and flow of chemicals in the
non living environment.

6. TYPES OF BIOGEOCHEMICAL CYCLE
 Gaseous cycle –Eg:Carbon cycle,Nitrogen
cycle,Oxygen cycle.
 Sedimentary cycle –E g: Sulphur
cycle,Phosphorous cycle.

7. CARBON CYCLE
 The cycling of carbon between biotic abiotic
system.

8. NITROGEN CYCLE
 The cycling of nitrogen between biotic and
abiotic system.

9. OXYGEN CYCLE
 The cycling of oxygen between biotic and
abiotic system.

10. PHOSPHOROUS CYCLE
 The cycling of phosphorous between biotic
and abiotic system.

11. SULPHUR CYCLE
 The cycling of sulphur between biotic and
abiotic system.
