THE CARBON CYCLE AND ITS IMPORTANCE


Carbon cycle

Carbon cycle: involves the series of processes which contribute to the circulation of carbon in nature.
i. Carbon dioxide is removed from the air mainly by photosynthesis during which plants use it to manufacture their own food.
ii. Carbon is lost in form of carbonates of calcium and magnesium through leaching and drainage
The atmosphere gains carbon dioxide through
i. Burning of fuel like coal and wood,
ii. The action of volcanoes which releases carbon dioxide
iii. The respiration by plants and animals
iv. The death, decay and putrefaction of plants and animals,
v. Diffusion of carbon dioxide form sea and other bodies of water, acting as reservoir of carbon dioxide

Importance of carbon cycle

i. Plants use carbon dioxide obtained from the air to manufacture their food during photosynthesis
ii. It provides carbon which is the major building block of all organic matters
iii. It helps to purify the atmosphere and also to maintain atmospheric level of carbon dioxide
iv. Organic matter which is made form carbon helps replenish the soil nutrients
