1. CARBON CYCLE

2. TIT BITS ABOUT CARBON Atomic no # 6a.m.u . Atomic mass # 12 a.m.u . Building block of all plants and animals.

3. DEFINITION OF CARBON CYCLE The process in which carbon travels ( in form of CO2 ) from atmosphere into organisms and earth and then back into atmosphere.

4. DISCOVERY OF CARBON CYCLE Initially discovered by JOSEPH PRIESTLEY and ANTOINE LAVOISIER. Popularized by HUMPHRY DAVY .

5. IMPORTANCE OF CARBON CYCLE This cycle is important for sustaining plant and animal lives. Plants utilize carbon dioxide and produce oxygen . Animals require oxygen for their living.

6. CARBON CYCLE

7. STEPS 1# Carbon enters the atmosphere as  carbon dioxide  from respiration (breathing)  and combustion .

8. Carbon dioxide is absorbed by producers (life forms that make their own food e.g. plants) to make  carbohydrates  in photosynthesis . These producers then put off oxygen.

9. Animals feed on the plants. Thus passing the carbon compounds along the food chain. Most of the carbon these animals consume however is exhaled as  carbon dioxide.  This is through the process of respiration. The animals and plants then eventually die.

10. The dead organisms (dead animals and plants) are eaten by  decomposers  in the ground. The carbon that was in their bodies is then returned to the atmosphere as carbon dioxide.

11. In some circumstances the process of decomposition is  prevented . The decomposed plants and animals may then be available as  fossil fuel  in the future for combustion. 

12. CARBON CYCLE IN WATER Carbon dioxide is utilized by marine plants .These plants are eaten by animals .As the animal dies the body is decomposed and carbon is returned.

13. Carbon is also stored at ocean floor as carbonate. Carbon is deposited in sedimentary level which is than liberated as the level decomposes.

14. HARMFUL ASPECTS OF CARBON CYCLE If any abnormality is caused in carbon cycle it can be very dangerous to living organisms. GREEN HOUSE EFFECT- if carbon is not recycled it can help in formation of green house gases. GLOBAL WARMING- without proper recycling of carbon can increase the temperature of earth.
