Observe the diagram and answer the given question. |
The amount of carbon dioxide in the atmosphere is regulated by which of the following? |
Plants Animals Oceanic reservoir of Carbon Burning of fossil fuels |
Oceanic reservoir of Carbon |
The correct answer is Option (3)- Oceanic reservoir of Carbon When you study the composition of living organisms, carbon constitutes 49 per cent of dry weight of organisms and is next only to water. If we look at the total quantity of global carbon, we find that 71 per cent carbon is found dissolved in oceans. This oceanic reservoir regulates the amount of carbon dioxide in the atmosphere . Fossil fuel also represent a reservoir of carbon. Carbon cycling occurs through atmosphere, ocean and through living and dead organisms. |
