Answers
Answer:
The carbon cycle describes the process in which carbon atoms continually travel from the atmosphere to the Earth and then back into the atmosphere. Since our planet and its atmosphere form a closed environment, the amount of carbon in this system does not change.
Explanation:
Carbon is a component of all organic compounds of protoplasm like carbohydrates, lipids, proteins, nucleic acids, enzymes, hormones, etc. It constitutes 49% of dry weight of organisms and is next only to water in abundance. Carbon cycling occurs through atmosphere, ocean and through living and dead organisms. A considerable amount of carbon returns to the atmosphere as CO 2 through respiratory activities of producers and consumers. Decomposers also contribute substantially to CO2 pool by their processing of waste materials and dead organic matter of land or oceans. Burning of wood, forest fire and combustion of organic matter, fossil fuels, volcanic activities are additional sources for releasing CCO2 in the atmosphere.
