Carbon Cycle

During the reactions which occur in fossilization of inorganic matter in the soil.

1. Carbon is deposited the sea bed.
2. They are decomposed by anaerobic Bacteria.
3. Dead organic matter exposed to high temperature & high pressure become hydrocarbons after millions of years.

Harmful activities that affect in the C cycle

Burning of fossil fuels,adding carbonic matter like polythene, polystyrene & pesticides like Aldrin, Diaidrine, toxifine which are not biodegradable.
